Mount for china laser pointer 303

thingiverse

This is a holder for the common china laser pointer "303" , that also keeps the on switch pressed. I needed this for mounting a pointer in a fixed place. The holes are placed so its easy to adjust the position then screw them in place. To switch the laser on push it further in the mount, to switch it off, take it out. Do not rotate the laser pointer while the button is in the mount or it will break the button. The device was printed several times and the tolerances are adjusted to my printer so they fit perfectly. However, you might need to adjust the inner size if your printer has bigger tolerance or you print at higher layer height (with less detail).
