Rachet knob for 18v ryobi multi size rachet PCL280B. Takes 2 8x3mm magnets. Center slot is a little snug but pops right on adding a slight friction fit hold along with the magnets.
printed well, large magnets should prevent it from falling. it’s a shame I forgot to check if it fits on my ratchets, the high speed hp and the lithium usb are unfortunately incompatible. But the print was great.
