Pretty fast reply:
"The SnaggletoothMF is injection molded of Delrin. Delrin is a very strong and resilient plastic. It has a natural lubricity and is impervious to most chemicals. Bleach seems to be it achilles' heel. Plastic springs and other high demand parts are made of Delrin because of it's great properties. We use only true Delrin which is a DuPont material. The SnaggleToothMF is very tough, not like a 3D print. If you order one, and are not satisfied we will gladly refund your money. I don't think you will be disappointed. Thanks for inquiring and I hope to hear from you again.
Regards,
Rob
P.S. Just to let you know, the molds, thumb studs, screws, stickers, Delrin and the actual molding of the parts are all American."
I think I'm going to give it a shot.
