These have been optimized for printing with PETG, which shrinks more than PLA. If you plan to print with PLA, you may have to download the files and scale by 1-2%, as the fit may be too tight. If you change the scaling, make sure you do so for all parts, so they fit together. 

I have provided a Multicolor(AMS) print profile and Single Color print profile. I have separated the Screwdrivers (¼ and 4mm), Keychain Caps, Gridfinity Base, & Base Holders into separate build plates. If printing from the Bambu Handy App, and you don't want to print an entire plate, you can delete the parts you don't want, or download the individual files & print that way. 

Each Screwdriver can be used with a Keychain Cap, the Gridfinity Base, or the Base Holder. Choose the correct size Base Holder for the amount of Screwdrivers you print (1-6). 

Although not necessary, the screwdrivers have a spot for magnets, to magnetize the bits or to hold them in place. For the ¼ bits, you'll need to use 6x2mm magnets. For the 4mm bits, you'll need 3x2mm magnets. To glue the magnet in place, stick it to the bottom of the bit, put a small dab of glue on the bottom of the magnet, and carefully insert the bit into the screwdriver and press the magnet in place. Make sure you don't add too much glue, otherwise you risk gluing the bit in as well.
