Parkside PASD 4 B2 bit adapter

Lidl's Parkside PASD 4 B2 cordless screwdriver is meant for electrical work and comes with six highly insulated proprietary bits, rated for 1000V. This is great, but it can't use regular bits. This adapter makes it possible to use the screwdriver with 4mm bits. Obviously, this configuration will not be safe to use with high voltages, but it will work as a decent generic screwdriver.

This has not been extensively tested, but with 100% infill and a tight fit, it should be able to handle at least light to average duties.

Update: I tried printing this in PETG using a 0.4mm nozzle, and the dimensions turned out incorrect. Needs some more testing. You may have to correct the diameters anyway, depending on your material and printer.

Update 2: I've done some testing with PLA and a 0.4mm nozzle, and found different values that worked better. I've left some of the test code in place, commented out, so you can experiment if necessary.
