We are. Of course. As part of the makerspace community, Workshop 88 has been participating with the Illinois PPE Network. The 100% donor driven, non profit endeavor. For more information, visit Illinois PPE Network.
Workshop88 members have been 3D printing face shields and surgical face mask extenders these past few weeks.
Here’s the latest news with the Illinois PPE group.
Due to the governor’s order to stay at home through the end of April, Workshop 88 will continue our suspension of public open house tours on Thursday nights.
We would still like to meet makers and connect with you! Please see our Meetup page for information on how you may interact with us including virtual tours and virtual open house visits on Thursday nights.
Like many Americans, my family had a spring break vacation planned just as the Coronavirus pandemic began to spread in North America. For weeks while looking forward to spring break we had been watching the dramatic growth of COVID-19 and steps taken to contain and control the virus in China, and more recently in Italy, Iran, and South Korea. We decided to cancel our vacation and begin social distancing. While disappointed, it was immediately clear that we made the right decision for ourselves as we would have likely been stranded away from our home in the USA and for everyone else in this time of aggressive spread of a highly infectious disease that hospitalizes 1 in 10 and kills 1 in 50 people.
We made our decision on Saturday the day before our flight was to leave, we all thought about social distancing and what we should do to protect ourselves and potentially others from us (two of us had recent colds and were uncertain if we caught it and symptoms were mild). Hand washing, not touching our faces, sanitizing everything around us were discussed, but when I found out that COVID-19 could last an astonishing 3 days on metal and plastic surfaces I immediately noticed all the doorknobs in our house. A doorknob you have to grasp with hour hand requiring a lot of contact, a door handle you can open with your elbow, or at least one finger. After you’ve been out in public touching door handles, railings, shopping carts, elevator buttons, ATM’s, money, gas pumps… You have to touch the exterior doorknob to enter the house before you are able to wash your hands, and everyone needs to touch it.
I also felt like I wanted to do something to help. I decided to design and share a customizable 3D printable handle that could be easily and nondestructively be attached to doorknobs. Not only are they more sanitary, but they turned out to be immensely convenient when carrying in groceries, or walking out with a beverage, etc. Below are links to my models and source code on Thingiverse, along with the write-up that accompanies them.
Updated stronger customizable doorknob handle with more options: https://www.thingiverse.com/thing:4228668
Note: Thingiverse customizer does not work with this model, it may be too complicated. Download Knob handle v5.scad*, open in OpenSCAD, and enable the Cusomizer UI in the View menu.

If you think these may help you, your family, or others, please feel free to customize and print as many as needed.
If you would like to manufacture and commercialize this product please contact me, we can work something out.
Novel Coronavirus or COVID-19 is spread like cold and flu viruses via contact with droplets (sneezes, coughs) from an infected individual. It has been proven viable in the air for 3 hours and has been demonstrated to contaminate surfaces for up to 3 days where it may be picked up on hands. A potential vector for infection is touching your face (mouth, nose, or eyes) with the virus on your hands. Frequent thorough hand washing with soap and water and minimizing touching your face are suggested ways to reduce the likelihood of contracting the Novel Coronavirus COVID-19 infection.

The use of round doorknobs require a hand to grasp and twist to open a door. Entry and exit doors in particular must be touched by everyone entering a household, are usually touched before having access to a sink, and after potentially touching public handles, railings, shopping carts, elevator buttons, ATM’s, money, gas pumps, rest rooms… Doors with handles can be opened with elbows and forearms which are less likely to relay infection.
This handle is easy to print and clamps firmly, gently, and non-destructively to round doorknobs.
An added bonus: Handles are easier to open while carrying packages, groceries, or beverages!
There are two styles, flat (push) and curved (pull).
The flat version will likely print more easily and is perfectly fine for doors that push open.
The curved version is tailored for doors that need to be pulled and in general is more universal.
I can open our doors inside and out with my elbows, but even if you can’t get your elbow in there, at least you can limit exposure to one finger rather your whole hand grabbing a doorknob.
You can customize the length, style, size of the doorknob and more in the OpenSCAD parameters in the file (even more if you dig into the code – have fun!).
The default size is 54mm diameter, 23mm thick doorknob. The model can accommodate slightly larger and smaller sizes as is.
To fit your doorknob you may either scale the STL file before printing (measure your doorknob diameter D and scale by D/54), or adjust the parameters in OpenSCAD, render (F6), save STL, and print your customized model.
The door handle may be installed horizontally but I like ours elevated (rotated “up”) 30-50 degrees to provide more of a usable rotation arc with my elbow.
Note, there should be enough friction to open the door with your elbow or knee
but the plastic handle may not be able to grab the smooth metal doorknob with enough force to secure it against any force without slipping. Simply slide it back to the original position or you can try installing a rubber band for more “gription“.
I will never know, but I hope this is helpful. I hope this has a chance of preventing at least one person from getting sick – even if it is not against Coronavirus, perhaps against one of the 200 viruses known to cause the common cold, or influenza (8,200 deaths in US in 2019), or Norovirus…
Maybe you just want to make it easier to bring in your groceries.
If you would like to support invention for the greater good, you can donate to your local makerspace… or mine: http://blog.workshop88.com/
(they will need support during these times of social distancing and isolation)
Also, please don’t judge my filthy garage/workshop doors too harshly… I have to go scrub them now.

Some makers are inherently social creatures and some makers are more introverted – but all makers are susceptible to the COVID-19 virus, and so we will be suspending our weekly Open House for at least the next two weeks – through the end of March.
Please check back with us for updates on how to engage with us – including all the usual ways.
Once you have the appropriate graphic for the special occasion, you can make it into a nice acrylic etched or laser cut decoration. Here’s an example of how to do that using inkscape software and the Full Spectrum Laser at Workshop88.
The first step is to find the right black and white clipart for your project. Assuming you are not an artist and don’t create by hand what you need.
Then from the menu select Path->Trace Bitmap.
Note the items underlined in red.
You should see the picture in the update window. If you don’t see the image on the right, start over and try again. Save the image as Optimized SVG. When you see the image in the update window, (give it a minute, watch the status bar) select the image (on top) again and move it to the side and then delete the duplicate picture underneath. Then move the image back to the center. Now you have the traced bitmap that can be saved as an .SVG file type.
That is your SVG image that will outline the letters and give you something to raster. The acrylic example below was done using raster settings only. For effect (and suggested by a member), light was shined through the side of the acrylic to make the image glow.
Or the wood version if you prefer.
When laser cutting, you learn the difference between raster and vector. The image was rastered first. Raster: Fast sweeps of the laser eye, over the wood to lightly etch away and burn the wood. And then vector (solid burn) just the outline of the letters to give it that extra stand out – outline. And the entire object cut along the edge with a hole for hanging on a hook. I prefer rounded edges for my projects so there are no sharp corners. And a hole for hanging the decoration. This image was well suited for that style.
In order to get the vector to outline just the letters, while in the Full Spectrum Laser software, Retina Engrave, you need to change the color of the letters. Then provide instructions for just that color. I made the word Thanksgiving in Yellow, just so that it was a color other than black.
This allows you to control the vector attributes for just the parts you select. Notice in the blue circle, the color yellow will only pass over once and the other colors red and black are set to 0 (zero) so that the laser will not vector those colors at all.
Whenever using the laser cutter, consult the document on workshop88.com Menu Item W88 Docs->Laser cutter to get guidance for settings. Always do a small test on practice material first. NOTE: Using the laser cutter REQUIRES training/certification of members, PRIOR to use.
Stop by on Thursday evening to talk about your project ideas and to see what is going on at the Workshop88 makerspace.
Don’t let the lack of daylight get you down. Start on that long list of projects or gifts and start MAKING. Get out of the house and join a makerspace.
Visit Workshop88 on a Thursday evening between 7pm and 9pm for a tour. See what we have been creating.
Visit Workshop88->Membership for more information and how to find us.
Because this Thursday is Halloween, we will NOT be having any open house hours this week. Please consider coming out NEXT week to learn more about Workshop 88!
