ProStruder filament guides

thingiverse

I've had ProStruders with Prometheus system for a while now and they work extremely well. However, sometimes when there's a filament jam or wrong feed sequence is triggered, the powerful steppers can push filament with such force that it 'spills' from the sides as the filament path is somewhat open due to the design. Also, PTFE tubes aren't that rigid, making this problem a bit worse. So I designed these filament guide parts. They replace following parts from the original ProStruder: - 4x M3 Washers - 3 Acrylic Tube Guides - 8 Acrylic 7.5mm Washers You can figure out what to do with those if you decide to do this mod. Assembling (see https://www.distechautomation.com/pages/pro-sys-assembly#2.03): - The lower guide part needs to be inside the idle part, and the bolt that mounts the idler to the motor needs to go through the idler and the guide part. - After inserting the top assembly, slide the top guide part onto the bolts (instead of the two original tube guide parts). For orientation, see that the gear and idler holes match up perfectly. - Proceed as in the original instructions. - When inserting the PTFE tubes to top and bottom, make sure to push them all the way to the guide parts.
