[Update]

I updated the print profile to include some TPU wheels. I split the wheels out from the main hardware, so you can print either the regular wheels, or the TPU wheels, depending on which you want. The plate with the TPU wheels is setup to print sequentially, and you'll have to print it twice for a full set of wheels. 

Fixed a few things with the instructions and hardware requirements. Incorrectly stated 6 bearings were needed, when I meant to list it as 12. I've updated the description and instructions to fix this error. 

[Introduction]

A cat exercise wheel! Round and round it goes, where it stops, only the squeaky bearings know. The wheel is roughly 43 inches across. 

The intention was for there to be a strip of carpet on the inside of the ring. the side guides on the ring were meant to help frame the carpet. At the time of taking photos, I didn't yet have a strip of carpet for this purpose, so didn't have it installed. 

[Printing Info]

You'll need about 6 rolls of filament for the wheel, and 2 rolls for everything else. From the print profile, you'll print every place once, except for the ring, which needs to be printed 12 times.

[Hardware & Filament]

My model is featured in Bambu's PETG-HF filaments. They're new at the moment, so I wanted to utilize them in some projects. Regular PETG, PLA+/Pro, ABS, ASA, PETG-CF, could all make good choices though. I would stay away from filaments like PLA Mattes, PLA Silks, and probably basic PLAs too. 

Featured Filaments:

• Bambu PETG-HF Black
• Bambu PETG-HF Gray

I use screws from Bambu's Makersupply, and mainly design around those, and recommend them. However, you can purchase self tapping screws from Amazonif that's easier for you. I'd recommend an assortment like this Amazon US. For sized screws, I have links below. )

• 86x BT3x12mm Self Tapping Screws (If you don't purchase an assortment or from Bambu, something like this should work from Amazon US)
• 20x BT3x30mm Self Tapping Screws (I recommend Bambu's 30mm M3 self tapping screws, but if you want to purchase from amazon, and don't want to do an assortment, I recommend something like this Amazon US. Finding self tapping screws in the 30mm length might be a little difficult, but these 20mm ones should work too. The hole is length for a 30mm screw as it'll go the whole way through the joint, but shorter lengths can work too and still function)
• 12x 608ZZ Bearings (8x22x7) (Skateboard bearings, like these ones from Amazon US)
• (optional) Carpet for the ring, for the cat to run on. 
• (optional) Glue to secure the joints.
