For Arendo 2kw mixer: the lid is not strong enough for my usage, so I printed one that is 6+mm thick everywhere

Print settings

  • material: PETG, also enable brim for the lid only and set to brim_width=10mm, brim_type=inner+outer
  • lid: 9 perimeters (to make it 100% solid along the top sloped part)
  • lid's lid: 99 perimeters (to add to only one model: right click, add settings, layers&perimeters) also to make it fully solid
  • supports: only for lid, “paint-on” only needed for the outside
  • 1.02 extrusion multiplier: surface will look a bit worse but layer adhesion and general strength should ++

Assembly: Use 3pcs M3 screws, M3x10 or M3x12, even longer works, and screw lid's lid to lid. I recommend to do that only once, as the screws will bite their own thread, which is intended as a permanent mount: do not unscrew them multiple times.

If you want it food safe:

  • Additionally, use glue before screwing lid+lid's lid it together
  • Use stainless steel screws
  • Paint the finished lid with food safe epoxy, probably 2 layers (24h curing inbetween) on the inside just to be sure an impact from inside the mixer doesn't simply chip off the resin

Final step: transfer the rubber seal from the original lid to this one

I use this mixer for grinding plastic to recycle 3d prints and it has been working great even though it was not designed for that. Hence these reinforcement parts
