This is a compact hamster wheel with a 170mm diameter, ideal for small hamsters or smaller golden hamsters.

It requires two 608ZZ bearings and no additional hardware components.

Design:

• The wheel is relatively small and may not be the best fit for larger golden hamsters, though it can still be used effectively.
• Sufficient cover pieces and secure fasteners are provided to ensure stability and durability.
• The front end of the central axle features a threaded cap for secure fixation, while the rear end is equipped with a threaded nut to prevent over‑extension and ensure proper alignment.
• Both 608ZZ bearings are fitted with dedicated retaining caps, eliminating the need for interference fits or adhesive bonding.
• The base employs a dovetail joint for quick and easy assembly.
• The front surface of the support structure is contoured to minimize friction while maintaining robust load-bearing capacity.
• The wheel wall boasts a thickness of 1.2mm and incorporates reinforcing ribs; the print path is optimized—only the inner and outer walls plus infill are printed, ensuring fast printing speeds without compromising printer longevity.
• We’ve carefully addressed potential issues such as bearing compression, eccentricity, and lateral wear that could lead to sluggish rotation, ensuring smooth and reliable operation.
• Some components may exhibit slight variations in tightness due to material properties, but this does not affect overall performance.
