All existing solutions for a filament holder on the Zmorph printer that I found, did not work out. Yet the filament flow is essential for a good, regular printing quality.
So I designed my own one. It takes every size of filament roll that I had. It works very smoothly, the prints are more regular now. Feel free to use it; any feedback is appreciated.
Whenever possible I use ABS
I used a "self made" graphical front end to OpenScad. It gives me fast access to some features like rotating, translating and coloring. It gives me the possibility to make parts visible/invisible and marked. Furthermore it shows me a construction tree and a library from which one can drag&drop new items. Parts that are used more often can be added to that library.
Anyone who is interested may contact me.
