This is a simple quick remix of Low poly Dart Wader from CalebTimoteo see: https://www.printables.com/model/553476-darth
You have two options:
1: print the original model and print separately the insert cup then glue or just leave as is as I did.
2: print the integrated version from here and have fun :)
Printed from eSun Black PETG, 0,2mm layer height.
