I became acutely aware that repeat parts on the Sculpfun iCube laser will require fixturing for parts placement. On my S30 and A9, I often just stick pegs in the honeycomb. I used Lightburn to lay out a method for fixturing in the hole located in the iCube base.
It is basically one 3mm sheet cut to fit the hole. A second sheet is cut out with a 4"x4" hole to act as a receptacle for a fixture. Note that the 188mm x 149mm dimension has not ben tested ( cannot until I return home). Once you have the two pieces of wood cut out, glue them together with opposing warpage. That should help the insert to remain flat over the long run.
The board now has a small pocket in it. Insert your templates or fixture assemblies in the “socket” and enjoy repeated positioning accuracy.
The provided Lightburn file should be ready for making the initial parts of your fixturing system. Adjust it to fit your own situation.
This idea is not original. I saw a guy with a Pecker or galvo machine showing off his system. His laser apparently had a hole in the base too.

Now I need to start looking for iCube hacks!
