Drop-in laser engraving bracket for Monoprice Select Mini by lacheur

Last crawled date: 3 years, 1 month ago

This is a printable bracket for a cheaply available 1000mw engraving laser, driven directly by the fan controller for the Monoprice Select Mini printer. Once connection wires are spliced, it's a drop in replacement for the factory fan. The same spring clips that hold the fan apply clip to the sides. Remove the fan, slide the laser into the bracket, clip the bracket, and connect the wiring.
At full power it draws about 1300mw (including fan).
This is designed for a 33mm square laser assembly with built in cooling fan, such as:
