My local library does 3-D printing for 25 cents per gram! This was my first print. :) I'm not sure who is more excited, me or my 6 year old son...

I printed two of the bearing caps. We test fit them in the bearing and they were nice and snug. Unfortunately when we went to pry them out for the final glue-in, they both broke where the hollow 7mm cylinder mates to the disc. I will have them reprint these, then apply some 2-part epoxy in the hollow. I'm a complete 3-D printing novice so I don't know if this is normal, it's something about their printer, filament, etc.

Thanks for all the customization you offer on this design!
