Smol Hub - .5"

thingiverse

The primary goal of these hubs is to offer a straightforward, compact, and cost-effective way to mount .5" thick foam wheels. Foam wheels are designed to fit snugly over the hub without requiring any glue, although you can choose to attach them with adhesive if you feel it's necessary. Once the wheel is in place, the hub will securely press onto your 3mm d-shaft. To achieve a tight yet removable fit, you may need to slightly expand or contract the shaft hole as needed.
