This is my version of a magnetmount for the hotend on a Prusa style machine.
You can screw it to the installed X-Carriage. The Hotend or Laser gets on a counterpart an is held in place with 4 5x3mm magnets.
The multimount has lots of holes to mount your current hotend mount or just a lasermodul.
The second Mount can be used for the hotend.
The baseplate has a mount for 12mm Inductive sensor.
The headchange is very fast and easy. Works really great.
Laser mount holes matches to the banggood 2.5W laser module and i think a few others.
