Time to Re-Caulk the Shower

It is time to re-caulk the shower stall so I wonder what tools I could 3D print to help with that job. Since the first step is to remove the old caulk, let’s start with that. Home Depot has a plastic tool.

I don’t need to buy that, I can make my own. But this gives me an idea for my first design. Next let’s see if there are any caulking tools on Thingiverse.

Search results for the word “caulk”

No tools for removing caulk so I will design one using TinkerCad.com. A handheld tool that can dig out caulk along the tile on one end of the tool and a flat end tool to get under the old caulk. Later, we will look at what other caulk related objects appeared on Thingiverse.

First iteration only took 47 minutes to print.

Iteration 2

Using the first tool, I discovered it was too short and the end was digging into my palm since I had to apply force when trying to remove the caulk. So for the second iteration, I made the tool longer and tried to round the end part that would be touching my palm. The red version took one hour and 18 minutes to print.

Additional Tools

The Thingiverse search results came up with plugs/caps for the tube mostly and some organizers to keep the tubes in order. There was no reason to 3D print a plug because there is nothing as perfect and simple as a roofing nail to keep caulk out of the tip and plug the end nicely. So I ignored those items on Thingiverse. I wasn’t organizing the workbench with several tubes of caulk so can skip those designs. But what was left was the smoothing tools. To be honest, this was kind of my first caulking job so I watched youtube videos before I started the project. The smoothing tools did come in handy to have. I would still wet them first as I would have my finger to go over the seam. But I was glad I didn’t have to use my finger and had the tool instead.

So in the end, having a tool like a 3D printer to print other tools does come in handy. You won’t be seeing the results of the actual caulk job. It’s too ugly. That’s not what I want to share for this project. As far as lessons learned and how I would do the job differently next time, I would a) keep the tip of the caulk tube smaller and b) wipe away the lumpy caulk immediately and try again.

The pointy ends held up fine. The slanted ends were starting to wear.
