Palette2 table top filament guides

thingiverse

I wanted to minimize wear and tear on my Palette2 Input drives when using them with a desktop stand. These guides utilize a small piece of PTFE tube to keep the filament path smooth. The PTFE is held in place by friction. High_curved_input: This takes filament from a higher input angle (if it's on a spooling system that sits high like the original Palette2 filament spool holder) and launches it at an angle suitable for the Palette2. low_straight_input: This takes filament from a low input angle and only has a curve on the output side to launch it at an angle suitable for the Palette2. Print at .2 with 2 perimeters and 20-25% infill. To Assemble: You will need some small lengths of 4mm OD/ 2mm ID PTFE tube. 1) Slide the PTFE in from the input side until it pokes out the output side. Give the output side about 5mm extra of PTFE sticking out. 2) Trim the input side flush with the holder To Align: 1) Slide some old filament through the guide and up into the relevant drive input gear. 2) Slide the guide down the filament until its base is flush with the surface. 3) While holding the guide, you should be able to remove and re-insert the filament with ease. The filament should find the drive hole by itself without any force being applied to it, or at least be very close to it! 4) Fix the filament guide in place. I used hot-glue; double-sided tape will likely work just as well.
