In my pursuit of getting ever better flight sticks, I recently acquired a Virpil T-50 stick that somehow needed to get mounted to my Obutto.
3D printing to the rescue: https://www.thingiverse.com/thing:2666670
Should work fine with the recommended print settings in PLA (slightly wobbly), but if you want to have a seriously rigid one, do it in ColorFabb XT-CF20. It is pretty much indistinguishable from steel for this application. Also, Copolyesters like E3D Edge or ASA stuff like MatX should work well.
ABS should also be doable, but given the size of the thing I’d expect warpage to be horrible to manage without an enclosed print area to keep temps stable.
In any case, enjoy!
