I've made this model to mount just laser module on custom Z axis modular support made by https://www.printables.com/@GregFRISON ( https://www.printables.com/model/367235-z-axis-modular-support-cnc )
Model with no gap (33mm space) might be too tight to mount laser in
So I made a model with 0.5mm gap
Printed with PETG
0.4mm nozzle
0.2mm layer height
30% infill
Use M3 screws both for mounting on support and for fixing laser module.
The author marked this model as their own original creation.
