Multi-Bit Precision Screwdriver (4mm bits)

This is actually three different precision screwdrivers that all look the same, but they are all a little bit different. They all use 4mm bits. They are: A fully print in place screwdriver where the bit simply friction-fits in to the screwdriver. (This is quite finicky, I recommend the models that use magnets) A fully print in place screwdriver where you need to pause the print to insert a magnet. A screwdriver that takes a magnet and needs to be assembled and glued. (Recommended) The spinning cap on all three screwdrivers is a print in place feature. Make sure your printer is well calibrated. You may want to print a partial screwdriver and test that you can free it up if you are unsure. If it does stick together, you may need to calibrate your extruder or adjust flow rate or something. You could also try adjusting horizontal expansion in your slicer. Temperature is also important. You need decent layer adhesion so the end of the screwdriver doesn't rip apart while you're torquing some
