Single, double, & triple thru-axle truing stand adapters (10, 12, 15, 20 mm)
Description
Based on the Problem Solvers truing stand adapters (https://problemsolversbike.com/products/tools/truing_stand_accessories_-_25444). Pictures used from the product page. There are a couple variants I published. The files can be trivially edited to make whatever set you want. Part files are available in double (only two hub sizes) or triple (three hub sizes) configurations. - 10, 12 mm - 12, 15 mm - 15, 20 mm - 10, 15, 20 mm - 12, 15, 20 mm There is an o-ring groove for an o-ring of 2 mm cross-sectional diameter. Get them in an nominal diameter slightly smaller than the intended thru-axle size, & it should stretch to fit. You may be able to get away with cutting pieces of inner tube as a substitute, or even forgoing any sort of retention at all. All interfaces have a diametral clearance of 0.1 mm built-in. Hopefully this compensates well for material shrinkage & dimensional intolerance. With good luck, it's already a very slight interference fit & o-rings are unnecessary. 24 Sep 18: added single size adapters in 12 & 15 mm sizes. I printed 12/15 mm adapter & the 32 mm length dimension was within +.05 mm, but I was seeing -.15 mm on the crucial diameters (11.75 mm instead of 11.90 mm = 12 mm nominal - 0.1 mm diametral clearance). These ones are oversized by 0.15 mm. I'll see what happens. I cut up a very small cross-section tube (700 x 19-25 is my guess) & it fit well in the groove on the 15 mm section. The 12 mm section was too small to accept any such o-ring substitute. 28 Sep 18: found a good diametral clearance. I've updated all the STLs.
