I love what @Judhini_1605028 did to create the original model. It was just too difficult to get it to roll smoothly. I added bearings and a counterweight.
I like to create 3D models that follow these criteria:
- Do not require supports – I HATE supports.
- Print quickly – optimized for 0.4mm nozzle diameter with 2 exterior wall thickness
- Are easy to access for maintenance – I like to upgrade parts, but I hate to disassemble the entire model just to change out one part.
- Are chamfered on the bottom layer – this helps those who don't have a perfectly aligned bed and may still have “elephant foot” artifacts.
- Do not waste plastic – many designers make parts that are WAY thicker than are required for structural strength. This just makes the parts bulky and take longer to print.
Notes
- NO SUPPORTS REQUIRED
- All parts print without supports.
- Tires printed with 95A Flexible TPU filament
- I recommend slowing down print speed and adding extra retraction.
- Requires 608-2RS 8x22x7mm bearings (qty 2).
- Requires nut counterweight (qty 1)
- There are 2 versions: ½ inch-13 or M12-1.75

Building Instructions
- All parts fit together snugly without any glue or screws.
