Description

I noticed that my printer struggled to pull the TPU when i tried to print it, so i decided to remix a spool holder and an attachment from the A1 mini to make this work way smoother. and it does, fits regular spools no problem and really helps with the TPU

Items need is 2x 608 Bearings of any quality

and maybe a screwdriver to remove the oem spool holder from the arm. If you look closely at your arm when you remove it you will see a small tab on the inside of the arm, press it and pull out the oem arm then replace it with this one!

Thank You. The problem with the design is, how @Minnieal28 and @fiocco10 stated, there is not enough room for the cross to go inside. I fixed this by drilling 1 cm inside the spooler, I did not wanted to print another one, it would be a quick fix directly inside the slicer. For the rest is perfect. Thank you!

Printed well overall. Should have used a retention clip like the original piece uses. The part that inserts to the printer is also longer than necessary for some reason.

(Edited)

Other Issues:Required significant sanding of the ends to prevent the outer race of the bearing from rubbing on the roller. Also, spools tend to slide onto the tops of the bearings, so the roller should have grooves or an hourglass taper at each end to center the spool.
