As the screws would slip off the idler in the Standard Airtripper, I changed the Idler to include a skewed front and longer slots for the screws.

I need to get longer screws, though.
The springs are from my scrap box, I believe from an old scanner or printer.

Sorry for my dirty workspace.


Just print the STL, the test is identical to the standard extruder.

Don't print the Axle, It's not a good fit. I've used a piece of 8mm Carbon-Tube, it will
fit perfectly to the Ball Bearing.

Really liked this upgrade thank you! I had to loosen the bolts quite alot since the force it puts on the filament is so big
