damped Tail Wheel for Multiplex FunCub

This is a spring loaded Tail Wheel Assembly for the Multiplex FunCub.
The Bearing was attached to the fuselage using Superglue.I made some Parts using ABS and some PLA, but i think it doesnt matter though which Material you use.
Additionaly required:
4 x Aluminium bolts 4mm x 30mm
1 x Spring 8mm x 0.75mm x 30mm
1 x Aluminium bolt 6mm x 22mm
A small Piece of Sheet metal
1 x small Screw
1 x Screw M5 x10
1x Aluminium tube 6mm x 4mm x 12mm

Cut a M5 Thread in the Aluminium tube and glue it into the "Lager" part.
Then glue the Assembly on the fuselage Tail.

Update:

Ive added the OpenSCAD File, so you can adjust the Design if necessary,
as with different Cura versions the size of cylinders and bores may differ.
