XL320 ollo pins

XL-320 servos are some of the cheaper smart servos available, but instead of using sane mounting solutions like bolts, they use plastic rivets.

Here are some plastic rivets that are compatible. They will hold a servo against a 1mm sheet with a 5mm hole. The pin can be inserted inside the clip to stop the clip coming un-clipped.

They can be printed at 0.3mm layer height it takes longer to warm up the extruder and print bed than to produce a couple of rivets.
