Braun Mixer M32 Helical Motor Gear

thingiverse

This is the helical motor gear for the Braun M32 Mixer. One version includes a hole, while another does not, allowing it to be printed without support and manually drilled. The inner 14mm ring appears too small for some users, necessitating widening either before printing or afterwards with a lathe. I printed this model using 0.3 layer height and an infill of 50%, which makes little difference since there's limited space inside to be filled. The 3rd 19mm rim lacks a proper surface on most prints, regardless of settings used. Feedback is welcome.
