YAFS yet another spoolholder

Spool Holder for 10mm thread and 1000ZZ Bearings made in OpenSCAD

i found this beautiful spoolholder https://www.thingiverse.com/thing:2070272 but since my available material
are 1000ZZ bearings and 10mm rods, and also purely, for learning purposes, i reproduced it in
openSCAD

i did it to be printed on a 3Dmodular Sclar XL premium, but failed miserably, had to let it print on a CR20 from a friend.... there it went without a glitch.
There are 2 holes in the Openscad genereated STL, that can be easily fixed on any web repair site, since i don't know where they are, i couldn't fix this in the source...

I know there are allready heaps of spoolholders out there, but i like that design, unfortunately the original inspiration was too small for my spools, and i had no 608 bearings, only 1000ZZ, i tryed to modify the stl in Blender, but failed miserably, so i redesigned the thing from scratch in OpenSCAD, with a lot of help from the community there, a big thanks to them! Especially to Dan Kirshner for his threads library!

feel free to make it better: https://github.com/nohkumado/spulenhalter

the final version was printed in .1 layer height and 20% infill, took 16h to print on a CR20 sliced with cura, didn't manage to get it printed on my printer (a Scalar XLP)
