Wore out the original wheelie bar roller and did not wan't to buy an entire wheelie bar set (LOS211046). Super simple design that does roll somewhat freely, and has a slightly larger outer diameter for longer life and to prevent the brackets from scraping on the ground. Recommended to print in TPU for better abrasion resistance.
Parametric file for Fusion 360 is included if adjustments are needed. Clears the Megalodon body, but does come very close to touching the tail.
The author marked this model as their own original creation.
