Prusa I3 Rework 40mm Laser Mount

thingiverse

I couldn't find an X-Carriage mount for the laser I purchased. It's a 450nm 5.5 Watt model, measuring 40mm square with a blue heatsink. I designed this part in Fusion360 to fit my Prusa I3 rework X-Carriage that features 23mm square hole spacing. Rotate the STL so that the M3 bolt countersinks face the bed. I will fix this issue in a future upload. To avoid any issues, you can try using supports for the M3 countersunk holes if necessary. I used Cura and set my horizontal expansion to -0.2mm. To assemble the mount, use M4 nuts and M4 bolts from the existing I3 rework X-Carriage. Use M3x12 bolts to attach the laser, as there are 7 bolt holes available but only a few may be required. I have successfully mounted the laser and it appears to be solid, but I haven't tested it yet since I don't have my protective eye glasses yet. Do not use a laser without proper eye protection!
