The model is quite big, scale as necessary to fit your needs. The one shown in the photo is scaled to 0.4 and printed with Creality Ender 3 V3 se.
The model needs quite a lot of support to print properly, but is worth the pain.
The rise of the spiral in the moebius strip is steep enough so that the gears rotate freely, giving an illusion that the moebius strip is flexible and twisting around the torus. Thus, the fidget is quite surprising to handle.
The author marked this model as their own original creation.
