Flik Wing Spar Mount for 20x20 Flight Controller

This flight controller mount can be used after the plane is assembled, and locks in place using the spar.

It mounts by inserting the top piece under the spar and lifting to fit the 3mm round spar in the groove, then sliding the bottom component underneath to lock it in place against the three retaining tabs. It's held well by friction, the spar and foam pressure, but you could use a couple dots of E6000 if you want to be extra safe.

Be careful, your spar is conductive. There is clearance between a MatekSys H743-Mini and the spar, but you may want to cover or insulate the spar anyway if you have a different flight controller or just to be safe. I have not tested this with other FCs, but I think any 20x20 mount should work.

Printed in ASA with short M2 heatsets (94180A307) and M2x8 screws (92832A111), this weighs 5g, so it's a little heavy. Other filaments should work.
