3mm nut driver with magnet slot

thingiverse

A 3mm nut driver to get into tight spaces. 3mm nut goes in the end, mine held the nut in place on its own, but i also added a slot for a 2x6 magnet that will hold the nut it place if your tolerances are a little loose. If you use the magnet you can just use the tool to get the nut started, but if you do not use the magnet, i have also left the inside hollow to 19mm, so you can screw down onto a 20mm bolt if needed. I may look at seeing if i can make the magnet easily removeable then you could use it to get the nut started, but take it out to screw the nut all the way down. I have not fully tested it, but i wouldnt want to put a ton of torque on the tool to get the nut super tight. For my usage i just needed to get it finger tight. PRINT SETTINGS: I used a brim just in case, and did not need any supports. Printed on a Bambu p1p at high speed without issue. Took about 50 minutes at 30% infill.
