This is an easy-to-use latch to retain Hexpansions in your Tildagon without needing to wrangle tiny bolts.
It needs 3 dowel pins, 8mm long and 1.5mm diameter, which pushfit into holes. The bottom two should stick out by 2mm, enough to go through the Hexpansion and into the M2 nut on the Tildagon.
Getting the dowels fitted can be a bit fiddly. I've printed a little jig to make it easier to fit the dowel into the rotor.
I'm printing this in PLA with 0.12mm layers.
I do wonder now if a slide-to-lock would be less fiddly to make than a turn-to-lock. I might try that next.
For an alternative with more clearance for components between the bolt holes, take a look at this spacer:
Many thanks to Ambrosia for the Tildagon CAD, which this was built to fit:
