I designed and built some stands for either side of the enclosure and mounted it on the top on the outside with some guides on the outside and inside. The stock is fed from the middle of the enclosure. I’ll try to attach some pictures, also I have a 13 second video of it working. Except for a few purchased items everything else was 3D printed.
I have the print files also. I haven’t taken the time to make up a good stock list or description.
Now to complicate things some more… I’ve pre-ordered the dual print head. Any ideas on how to mount TWO spools inside the enclosure? Also, every solution I look at has the metal spool holder being re-used but I can’t seem to buy one. Maybe it’s time to look at milling metal with my CNC?
