Summary

This is a spindle and/or laser holder for a small CNC (SainSmart Genmitsu CNC). It is for use when you swap out your spindle for a laser and you need to store the spindle (or vice versa). It should protect them well, including the lens on the laser. Its made to mount on the back of the machines upper rail using M5 screws and T nuts. In the download there is also a 2 bin version also if you want to store both laser and spindle or store one and put the wires from the device in the other bin. Note the 2 bin version has smaller holes, but could be drilled larger. (It was intended to mount on a acrylic plate I attached to the rails to bolt various devices on.)
The 1 bin version prints nicely in the vertical position without any supports. The 2 bin version requires supports turned on.

This was printed on a Ender 3 Pro in PLA at 0.2mm
