Helical Gear Clock

A two part helical gear clock with optional blanking disc for the center hole. This is compatible with the quartz clock included with the Bambu Labs A1, or most other similar clocks. You will need an M5 threaded insert and bolt (about 10-15mm is enough) to attach the bottom piece to the clock face. These can be easily be installed by heating a soldering iron to about 230c and pushing it gently into the hole at the bottom of the clock, until it is flush with the start of the hole.
