Screw clamp wire holder
thingiverse
Tired of all my wire holder clamps coming loose and falling off my table from the PLA stretching overtime. So I designed one where you can tighten it as much as you want. Basically a C-clamp with a wire holder portion on the top. Fits 3 charging cables with a max diameter of 4.2mm, and a table thickness of around 35mm. No supports needed if you print in the orientation like in the photo. the cable holder portion is somewhat hard to push in. but it always seems to push in fine. Maybe you'll need to file it down if your printer is not dimensionally accurate.
