2x4 base caps

I was building a bunch of 2x4 shelves in the garage and needed caps to keep the ends of the 2x4s off the ground. I got a little carried away with the various screw hole options, but it should support any future projects. I’ve also attached the OpenSCAD file in case anyone wants to tweak it to their own needs. Please be gentle when criticizing my code as I’m not a programmer!

This should fit nicely on most 2x4s (at least all the samples in my garage.) It has a 91mm x 40mm opening, which gives about 2mm extra space. If you are printing with plain ABS you should scale it up by 2% or so.

All holes are staggered so screws won’t hit each other or cause a split in the same location. Standard 1 1/2” wood screws are recommended.
