OpenAstroTracker 608 Ball Bearing Mod
thingiverse
Modified parts to allow the use of more common 608 ball bearings **Both splitrings have to be printed with supports enabled.** The ball bearings on the rollmounts need to be inserted in the 608_spacer.stl to get the same diameter as the original ball bearings.  I haven't tested the tracker with the 608 ball bearings yet but everything fits together nicely and rotates smoothly For now, I only modified the 50° parts but if there is demand I can modify the rest of the parts too Update: 30° parts added slots added to angle 30° to add hexnuts in the part added holes to 30° angle and rollmounts to reinforce the ballbearing shafts with nuts and bolts
