Didn't feel like spending money on linear bearings so I thought I would give this a try. They work pretty awesome.
These are being used with OPENBEAM extrusions so you might not have too much success with other brands.
Change #define DELTA_CARRIAGE_OFFSET to 18 and use the new top pieces if you only want to use one idler bearing on the belt. You can keep stock top piece if you use multiple idler bearings but you will get some binding at extreme height.

EDIT: I soaked them in vegetable oil for a little bit after printing and they run really smooth.
Should have stated originally this is for 1515.
