M6 star knob w. through hole and nut-insert / Sterngriff mit M6 Mutter-Einsatz durchgängig..

This M6 nut handle, which consists of the main body and an insert for a nut itself, was made in a series of replacement parts for different cars. This part can be used for instance for a rear lights hub in some of the citroën c3 (2010-2016) or for any other application. 

Although the handle was made for a roughly 5mm thick nut, a bit thinner nuts could work as well.

Printing tips (especially for beginners in 3D-printing):

I would suggest to print the parts using something like TPU or PETG (both of which have been successfully tested) but also any other plastic applicable for durable mechanical parts.

The main part of this nut handle should be turned "upside down" and printed using standard supports.

Tips for printing with a single material – in order to avoid problems with supports removal: apply maximum cooling for the layer above the supports (in cura this settings get activated with the "fan settings override" and the corresponding temperature field options within the supports section) and also ensure that the (connected) support lines/zigzags don't run in parallel to the overhanging layer lines, as to be seen at the second Orca-slicer screenshot (supports are shown in green, overhanging layer in dark blue).

Have a nice print!
