As you can see on the video the main body is printed from PLA
The rotating part can be print from PLA also or with TPU:
If u want to print from TPU use file with 'TPU' in the name, - this is just a little bit longer
If u want to print from PLA use file with 'PLA' in the name, - this is shorter one
If PLA file is not long enough you can print the TPU version with PLA filament.
-Printing from PLA use 100 infil it wil get better stiffnes
U need also M3 16mm bolt and nut.
