This is a slightly larger version of my Finger Treads model. I don't think it makes as good of a fidget, so I am going to leave it as its own model for now, but it still very satisfying to play with.
If you are having trouble with pin durability or parts fused together. This model is enough larger that it tends to be more forgiving.
There is a normal version with 0.2mm gaps between pins and holes, and there is an extra clearance version with 0.3mm gaps.
Here is a size comparison for reference. XL version top and original bottom.
