Drop-in laser engraving bracket for Monoprice Select Mini

thingiverse

This is a printable bracket for an affordable 1000mw engraving laser that's directly powered by the fan controller of the Monoprice Select Mini printer. Once connection wires are spliced, it becomes a seamless drop-in replacement for the factory fan. The same spring clips used to hold the fan can be applied to the sides of the bracket. Remove the existing fan, slide in the 33mm square laser assembly with its built-in cooling fan, secure the bracket using the spring clips, and connect the wiring. At full power, it consumes approximately 1300mw (including fan). This design is tailored for a 33mm square laser module featuring an integrated cooling fan.
