Bore Inserts for 3D Printed Parts

Need to use a 3D printed part on your hex, keyed or Kraken shaft, but the bore keeps rounding out? Well, here’s your solution - 3D Print Bore Inserts. Simply design a tight press fit into your 3D printed part, press the insert in, and let the print retain the insert. Now your 3D printed part has a nice metal surface to react to the drive shaft with, allowing you to drive that 3D printed part for thousands of cycles. These parts have a boss around the bore on one side allowing you to put them directly on a bearing race and not rub. They are designed to be used in pairs, one on either side of your part with the bosses pointing outward.
