Ab Wheel (Ab Roller)

thingiverse

Ab Wheel for Your Core Workout. The Ab Wheel (Rad.stl) stands at a height of 25.3 mm for standard linear bearings. You can scale the wheel and tire (Gumi.stl) in Z height to suit your needs. I printed one wheel (gold) with a height of 25 mm and the violet wheel with 20 mm to achieve the 45-46 mm required for the Extended Linear Bearing Type. The tire was scaled up to 46 mm. Tip: Run a test print on the handles to ensure that the 8 mm shaft fits securely. Print (Griff innen.stl and Griff aussen.stll) with a height of just 15 mm and test it on your linear shaft. If necessary, scale the part by 1% or adjust your flow rate.
