Screwdriver bit for step drill

thingiverse

So I needed to drill a 1/2 inch hole to make some airtight filament canisters but I had no power tools for my step drill. So I designed a screwdriver bit to hold the step drill =) It can be very strong when printed with 80% infill. However, you must apply pressure correctly (i.e. not on the x/y axis) or it may break. Also, I suppose you can drill harder materials but it will take much longer. It was great for soft materials like plastics! Also, this is made to be tight fit so the step drill/screwdriver bit doesn't fall off by itself. Lower the scale if it's too tight for you. =) Print Settings Printer: Monoprice Maker Select V2 Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.1 mm Infill: 80% Notes: No need for brim or raft when printed with PEI. However, with the small surface touching the build plate, you need your bed leveled correctly for maximum adhesion!
