This is a grinder cookie/puck I found on Printables. It's used to safely and ergonomically push stained glass sheets against the grinder bits.

I printed this with TPU 95A. I was concerned about printing the screw in TPU, but it turned out great!

I uploaded a separate print profile that contains a pause. I used this pause to switch TPU mid-print with PETG. This can't be done with AMS, because the AMS is not compatible with TPU filaments. I didn't have to change any settings for PETG and used the same calibration settings as my TPU filament:

• Hatchbox TPU 95A
  • PA: 0.2
  • Flow Ratio: 0.955
  • MVS: 3.2 mm³/s
  • Dried 24h prior to printing, and printed straight from drybox
  • The rest are default settings from the “Generic TPU” filament profile
• Kingroon PETG
  • Exact same settings as TPU were used 😱
