***ATTENTION:*** I cracked the top acrylic panel while mounting it to my Makibox. It's not a serious issue, but if you want to avoid this problem, be extremely careful when inserting the mount through the hole in the top where the bowden tube and wires used to pass through. The "thin" parts are for using the same screws that the Makibox originally used for the extruder, allowing you to add an additional plate. The standard parts are too thick to use with the original screws and a cover plate. I left these standard parts in, just in case anyone is printing them with a stronger material that won't require a cover plate to secure the arm. I was one of the lucky few who received a Makibox before the company went completely bankrupt. It's a decent system, but it has several problems. One of them is the extruder, which I decided to upgrade to make it usable with flexible materials and to use the three existing screws that ate through the plastic they were mounted to. I've also included the base with and without the mounting for the Makibox in case anyone wants to use it on a different system. Since the accuracy of the Makibox is kind of poor, the tolerance for the parts is 0.2mm for almost all of them. I still had to drill out most of the screw holes and filament paths to get anything to fit properly. The holes for the bowden adapters may be too large for those with high-end machines. After using this extruder a bit, I noticed that its strength in PLA is not great. It continues to work, but I don't like how the arm deflects away from the path of the filament. I think I'll add a cover plate at some point to keep everything aligned properly. I've added several versions of plates for the option to have a window or not as well as an alternate mounting method. I spaced the holes for screws to fit the two screws in the top right back corner of the Makibox, but it could be used to mount it to aluminum extrusion lengthwise as well. I also fixed the inlet and outlet sizes for the bowden adapters, which were a little too large for threads to grab onto. After printing one of the plates, I realized that the spacing was wrong for the holes. That has been fixed. Once I have a chance to test it fully, I think that will be it for edits to this thing unless anyone has anything they would like to see changed or added. Let me know if this helps any of you print better and more flexible materials on your printer. I've done a lot of printing with flexible material at this point, and I think this can be a finished project.
