Quick release mount for Virpil collective to Monstertech chair

In case you got this combo and dont want to use native solutions for mounting this thing, here is an adapter I'v put together while waiting for the collective preorder to arrive.

There are multiple ways to mount this thing, but the one shown in photos works best for me. Not too far from the side and the height is just right. 

You wont need any additional bolts as it mounts using the ones which come bundled with it. It might be a bit tricky to tighten the bolts as shown in the pictures, so if you fail there, the model got the square insets for the bolts, so should be ok to put washers and nuts on the metal side of things.

I've attached a PrusaSlicer project, which got some custom infil tweaks for the screw base. Printed in PETG but  i think PLA would work as well, as there isn't much stress applied really.

You can see it in action here

2022/04/18 Updating the adapter to be slightly thinner (the default bolt is rather short and a few extra mm do make a difference). Also adding a round cutout to the adapter and a model of the tightening mechanism handle, which is slightly thinner than the one which comes with the chair. The cutout and a thinner handle allow mounting a cm or two closer to the chair. Also handy if for some reason you break it ^_^. The original handle is nylon with fibreglass (pa6gf50) but other materials work as well. I got it printed in eSUN PLA-ST and it seems to hold.

2022/06/21 there is a new version of the armrest handle here
