In principle, no. The reason I made them was that I’m a cheapskate with a 3D printer, and I baulked at the price some of the (Etsy?) sellers were asking for these! I’m more than happy, though, to share the .stl file so you can print your own, and I’d happily make the odd pair really as a favour - I’ve just got no ambition to let this become a business.Do you sell these? Great design!
By all means PM me if you’re interested.
