Upbox+ extruder mod for TPU UPBOX / Afinia H800

thingiverse

Tired of struggling to print with PTU on my UPBOX+, I finally decided to take matters into my own hands and create a mod for the extruder, as no suitable ones were available. The spring used is 7mm in diameter, while the original bearing remains intact, and the nozzle was drilled out to 1mm. To accommodate the lever, an area was carefully cut out of the print head cover's side. So far, I haven't tested this mod with Ninja Flex, so any feedback from those who have would be greatly appreciated.
