4 40mm aluminium profile end caps (40,80,120&160)

Update; the first layer is now 0.1mm high so it blends better with the starting layers.

---------
Aluminium profile end caps to pretty up those ugly bits on your sim rig or whatever you're using 40mm aluminium for.

Fits european (UK) profile well but if you want to change the fit, just edit the diameter of the connectors slightly.

No supports needed if you print below 0.2 near the bottom of the print, i used a variable layer height in the 3mf file that works well.
