Own design , inspiration from the teigblume tm5 / tm31.
This is for the kitchen machine thermomix TM5 and TM31.
Update for the TM31, you can shrink it 10% then it fits perfect.
i will update later with an separate file for TM31 ,
It helps toget the doug out off the tup. by twisting the knife . Mirror this for Righthanded use .
2 sorts i prefer the 40mm , is more friendly in use .
The designs on the net are not 3D-printer friendly , this one is printing without any support.
I made several from this, all in PLA , 40% infill 0.10mm hight with 0.30mm nozlle, works perfect .
