The file 'Bike Bell Lever With Magnet Hole 3D Printer Model' is (blend,stl) file type, size is 158.7KB.
My son's bike bell lever has a built in magnet that activates an LED light show when he rings the bell. The original print had a small lever so I beefed it up and added a hole for the magnet. I did need to heat the PLA a bit to force fit the magnet.
