got the idea from this video: https://www.youtube.com/watch?v=sNh0ubRcTYU

You can easily change parameters with Fusion 360 and fusion file

You will need:
8x 625zz bearings (5x16x5mm)
16x M5 washers
4x M5 bolts (min. 35mm)
4x M5 nuts
6x M4 bolts (lenght in Body2 section)
6x M4 nuts
2x M3 bolts (lenght in Body 3 section)
1x M3 bolt (8-10mm)
1x M3 nut
2x rubber bands


Print settings:
0.2mm layer height

Body1:
-only part that needs supports
-pause at layer 93 so you can insert 6x M4 nuts during the printing
in cura: extensions->Post processing->Modify G-Code->Add a script->Pause at height->Pause at: Layer No. and Pause Layer: 93
-first layer after the inserted nuts will be probably printed badly, but it fixes itself after that

Body2:
insert=anything you put in (rod,pen,...)
-M4 bolts lenght:
ver.1=30+insert diameter
ver.2=20+ins
