This is designed to hold six screwdrivers whose shafts are 100mm long or less. It's very simple in design.I recommend printing with a significant brim in order to prevent curling. Additionally, I printed it with 20% infill, as it doesn't need to be super super strong to do its job well. Printing it on its top will likely result in a prettier object, although I designed it to print on its back to give the greatest strength in the downward direction.
