This is a small shelf to hold 3 precision screwdrivers for the amazing #Multiboard (Thanks, Jonathan!!!).
I had too many of those flying around and wanted to hang them where they belong. There are two sizes to fit the larger and the smaller screwdrivers.
The larger has a 6.8mm slot for up to 6.5mm thick screwdrivers, the smaller has a 5.2mm slot for 5mm thick or thinner ones.
The shelf can be stuck into the small holes and just hangs there. No need to print any screws or other parts for attachment.
