[Woodworkers] Table saw gripper push block, 3D printed

[Steve Bigelow]

Little assortment boxes like these come in handy for organizing my small
screws, nuts, bolts. M5 is about the limit, though. Lots of different
container sizes, and the smaller ones have lids.

I need to make a little wooden cabinet to hold them. I'm thinking 1/4"
shelving, 1/2" sides. A little carrying handle on top, and some sort of
slat arrangement in the front to keep them from sliding out while I'm
carrying them. That stack is going to fall over one of these days, and I
won't be a happy camper.
