Prusa I3 MK3 Parametric OpenSCAD Remix

thingiverse

Originally I simply wanted to modify the position of the X axis idler, however the original Prusa OpenSCAD code makes it difficult to make changes because most dimensions are used directly. That's why I've decided to rewrite all parts, driven by parameters stored in a single file. [OpenSCAD code here](https://github.com/puddnig/Prusa-i3-Parametrized/tree/MK3/Printed-Parts/scad) Currently I've rewritten the following components: * #####Z-Rod Bottom The Stepper is centered as in R2 of the original part. The front was also cut to make it easier to access the bolts behind the stepper. The chamfer on the outside ends flush with the frame. * #####Z-Rod Top The original part is a bit flexible left to right because of the cutout in the top and the narrow connections. Also the chamfer on the corner should end flush with the frame. * #####X-End Idler The idler is mounted 2 mm further upwards to make the belt parallel with the X axis. The cutout the idler is mounted in looks less "patchy". There are integrated bearing spacers in the bearing housing. * #####X-End Motor and X-Tensioner I've added a tensioning mechanism with a bit more range and control. * #####Y-Motor Holder The stepper mount is adjustable, so you can move the stepper directly against the frame. * #####Y-Belt Idler Changed height of idler to make belt parallel with the Y axis. Also there are added bridges to prevent the side mounted to the plate from getting convex when tightening the idler. * #####Y-Belt Holder Changed height of the belt slots to make the belt parallel with the Y axis. * #####Y-Rod Holder No zip ties anymore. The part also employs a new technology called rounded corners. * #####Einsy Base* No needed changes, but it is fully parametric now and the code is a lot shorter. * #####Einsy Doors* The same as with Einsy Base. I haven't gotten around to rewrite the X-Carriage but I've fixed the original stl's for a parallel X belt. Parts marked with * have not been tested yet, but might work.
