Thanks to MaxxTek for discover a design error affect to the slicing process, i correct the model and the STL. Published V2
First, sorry for my bad English.
Is my first work for my printer, and my first work in FreeCad, (i include the freecad files), feel free to modify.
Is a gothic work, is my style.
The design fit perfect on Anycubic kossel plus
I first design the spool based on 608 ball bearing, but after try it i decide redesign for a hard disk bearing, the difference is important, more stable and go perfect. (include all the versions, i recommend the Hard disk bearing version)
When you have the hard disk bearing is necessary edit the spool in the file Freecad for the bearing dimensions, and recreate the stl.
The model is designed for spool hole diameters from 62mm to 42mm.
For a perfect and smooth feeling is important move the bowden to the top of back tower i publish in a future model the work.
Please feel free to modify the work.
This list of great works brings me the complete work and i think is necessary recognise.
