D shaft to 25T adapter?

So it looks like I accidentally ordered 5 pair of these:

Instead of these:

Any way to exchange them or buy an adapter to make use of the d-shaft motors I have?


You can review our return policy and see if your items qualify at the bottom of our Ordering page here.

Those 90mm servo wheels will work with our Universal mounting hubs for 6mm, 1/4", or 8mm shafts, so if your motor shafts fall into one of those sizes, that could be an option as well.


Yeah, I ordered these back in August or so, so I guest returning isn’t an option. I have a 3mm diameter shaft. Its those micro gear motors with the d-shaft. I guess I can print something to fit the 6 mounting holes to a d-shaft as a work around.
