Wanted a little extra grip skinning up the backcountry. Designed two versions to work with my Marker Kingpin bindings mounted on 115mm wide skis. Printed with Nylon and continuous Kevlar fiber with my Marforged Mark One printer. Wouldn't use on glacier ice like metal crampons, but they will work nicely on hardpack snow to give extra grip beyond regular skins.
Designed on FreeCAD.
The two piece design is fastened with four M4 12mm bolts.
Update: Refined the design after field testing. v3 files. Also includes a version for 100mm wide skis.
