Plumber's Can Opener

I designed this thing to open "brush-in-can" plumbing adhesive containers. These adhesive containers use a standardized 45mm diameter knurled lid. The lids usually become impossible to remove with bare hands after the threads get jammed with glue (often after the first use in my case). So I keep one of these tools handy in the box where I store my plumbing sundries; it easily beats having to reach for the slip jaw pliers.

No supports are needed. I printed my tool in ABS, 0.4mm nozzle, .45mm line width, 25% infill, with 4 line walls. The result feels good in my hands; ie it is very tough/durable, yet easy to squeeze tight for a solid grip. Other filaments will work, but semi-flexible filaments like ABS or nylon will make a tool that is easier to squeeze, versus stiffer stuff like PLA.

A side note:

Some plumbing sealants come in containers with smaller diameter lids, like Rectorseal No.5. For the most part, these jars with smaller lids are generally not troublesome to reopen. So I didn't make a tool for those, however I did make the model parametric in freecad. So if you have a need for a different size, leave a comment with the size you want and I'll upload more stl's.

Enjoy!

[edit: Per request, I uploaded an version 2 file with longer handles.

edit2: Per another request, I uploaded a version for 1 3/8" lid cans (35mm).
