Thru-axle truing stand adapters

Adapters to make it easier to true thru-axle axles on a truing stand.

I looked at the Park Tool TS-2TA product, & decided I could integrate the spring & spacer piece into one overly-complicated stacked wave spring. Based on overall dimensions from the TS-2TA.

The spring spacer has a chamfer to make dropping in the adapter easier. I don't know if this would work with non-Park Tool modern truing stands.

This is untested.

Assembly

You will need

- seatpost clamp quick-release M6 skewer (52.5 mm length - cut down & cut more threads if needed) & concave washer

- M6 nut

- spring spacer, printed

- interface, printed

to make one adapter.

I recommend small layer heights on the interface piece since it will be the contact with the hub axle.

The interface has a deepened M6 clearance hole so it can accommodate some variation in skewer length. I don't have one on hand, so I don't know what the standard length is.

If it's too long, then the spring spacer file will need to be edited appropriately.
