The file '22WMR Bullet Holder 3D Printer Model' is (SLDPRT,STL) file type, size is 658.5KB.
This is a sliding lid box for holding 50 rounds of 22WMR rimfire ammo, similar to my previous 100 round 22LR Bullet Holder.
No special instructions other than using a 0.2500" reamer (preferred) or a 1/4" drill bit (works as well, just not as smooth) chucked up in a drill to clean up the holes in the bullet trays, then using 220 grit sandpaper to smooth out the sides and edges before using them.
I like to print the box in bright neon colors, and the lids in either transparent clear or transparent black. The trays I have printed both ways, and it really depends on what is in the printer as to whether they get the lid color or the box color.
