* [Livhaven](https://store.livhaven.com/r053010810-bosch-rexroth-ball-transfer-unit) - US-based. Doesn't require company information, but overseas shipping is expensive.
* [Uberbearings](https://www.uberbearings.com/R053010810KU-B8-OFK-BOS) - Ships from UK worldwide to private customers. Much cheaper shipping than the other Europe based ones.
* [L-System](https://l-system.nu/webshop/linear-technology/ball-transfer-units-and-tolerance-rings/ball-transfer-units/type-r0530/ball-transfer-unit-ku-b8-ofk/) - Sweden-based. Might allow private customers to buy.
* [Spareparts](https://www.sp-spareparts.com/en/p/r053010810-bosch-rexroth) - Ireland-based. Ships to UK and maybe elsewhere. Does sell to private customers.

* For other sources, try Bosch-Rexroth's [contact locator tool](https://addresses.boschrexroth.com/) - find a distributor near you, and search for the bearing part number on their website.

(Some people consider buing cheaper nylon BTUs. But they have high internal friction and the ball actually slides on them like on a static bearing, which makes them pointless.)

## Printing
Follow [Ploopyco's recommendations for print settings](https://github.com/ploopyco/trackball/wiki/Appendix-B%3A-3D-printed-parts). It's also highly recommended to enable support interface and splitting the support into chunks, as otherwise it can be very hard to remove.
