Made for BBB by experienced antweight builder Mike Brazier, these are a drop in replacement for the much loved discontinued ToughHubs from our friends at Nuts and Bots. DuraHubs are a high grip silicone treaded wheel on a 3D printed PLA-ST (super-tough) hub that’s well suited to antweights running N10 or N20 gearmotors. New for 2026: upgraded stronger keyed in tyre attachement – hubs are marked with “II” to indicate this. CAD STEP files: 25mm, 30mm, 35mm. Example robot below.
