<b>First off...</b>
You cannot use the online Thingiverse Cutomizer to manipulate the SCAD files. You have to <b>use OpenSCAD</b>.
I decided to make every piece I use - except the tower - an OpenSCAD design.
This decision is mainly driven by the idea to add limit switches to the axis to prevent the machine from banging into the endstops. I was unsure whether I am able to imagine the correct postion and orientation of the additional parts and moreover to prevent intersections.
As for now I have a working version made from the original files of squadzone. But I had to change the gliding blocks to fit to my spindles (that was the initial reason to try building this gadget parametric). Strictly speaking I resiled from this heating procedure to adapt the gliding blocks to the spindles.
One big concern with the original design I had with the holes for the screws to put all parts together. I normally use M3 countersunk head screws, so I had to manually countersink all holes. Consequentially I changed all holes to countersunk holes (only the top side where the screw head sits 😉).
In the devolution of the project I added more and more parts to the OpenSCAD process and in the end I even rendezvoused all parts in an overall assembly and added rods, bushings, the fork light barriers and the screws as adjustable interrupters (see picture).
In the resulting model I perceived that the screw heads would touch a part of the tower, so I had to change this part of the tower.
Since my…
