I've found this great model by @jonathanlevi and printed it first before measuring my srewdriver. Always a bad example of how to do things.

So please grab a caliper and measure your screwdriver before printing. It fits up to 18.5mm round electric screwdrivers from Temu or AliExpress.

It can be printed with various materials. For a smooth finish I advise using Adaptive Layerheight and ironing the top surfaces.

NOT REQUIRED but optional:

This is a gridfinity 5x2 print with magnet slots. It has slots for 6x2mm magnets, 40 in total.

Please find the parts below or in bulk at your online or local hardware store.
