The holder is currently being evaluated in one of the children’s rooms.
If it fails, I will blame it on them 😛

The OpenSCAD source file contains descriptions for every
single variable and should (TM) be self-explanatory.

The special variable PRINTPART, somewhere around line 70
allows you to switch from edit to print or test-mode.

// ============================================
// PRINT/EDIT PART
//
// 1 = EDIT -> use this to edit/tune the holder
// 2 = TEST PRINT -> very small print to check clamp dia.
// 3 = REAL PRINT -> use this to export the STL model
//
PRINTPART = 1;

If PRINTPART is set to “2”, only the (half of a) rod clamp will be generated. This might come in handy to manually tune the clamp diameter to fit the rod.

Be careful with angles > ~70 degrees:

– the holder might not be strong enough
– by design, the thickness of the top part may vary
