Tool Holder

Designed to fit onto the edge of a particle board desktop. Can hold a hand tool and can be easily moved to another location. Bushings can be used to reduce inside diameter.
The first one requires no support.
The second slotted one will but it's quicker to print the first one and nip out an opening with wire cutters; you decide.
Gap is 19mm to slide over a slab of particle board and tool holes are 12mm dia.
The third one has an 18mm gap to fit 3/4" plywood
First bushing has 10mm opening for smaller diameter handles.
Second bushing has 3mm opening and is longer to support tiny screwdrivers. Added length keeps them from flopping around
The small hole in the top of the holder is for a thumbtack for added security.

-Uploaded Hammer_Holder. The two pieces can be joined with a pair of M4 flat head screws and nuts for added strength. It's just big enough to hold a tack hammer.
