Description

Litter Locker replacement cartridge that's easier to refill and hold 3rd party bags.

Onshape Design: https://cad.onshape.com/documents/07ab47c35c3128c157430561/w/28c064530f865ed22cb78021/e/ce07d39cc888c5b0eef8d20f?renderMode=0&uiState=658acdcba6dbf37d9b7ddde1

 

Improvements over re-using an old cartridge:

  • Doesn't break easily (every break can easily tear the bag)

  • Easier to refill as the inner hole is slightly smaller than the original

  • Top fits easier and more sturdy as the original single-use cartridges

 

Print-tips:

  • Print the bottom part upside down

    • Doesn't need supports, a little bit hanging bridges are fine (there is a support structure included)

  • You can print with the largest layer height possible (works with 0.32 structural)
