OpenAstroTracker 608 Ball Bearing Mod

thingiverse

Modified parts have been altered to accommodate the use of more common 608 ball bearings. Both split-rings must be printed with supports enabled in order to achieve optimal results. The ball bearings on the roll-mounts require insertion into the 608_spacer.stl file to obtain the same diameter as the original ball bearings.  Initial tests indicate that everything fits together nicely and rotates smoothly, but further testing is necessary with the 608 ball bearings. For now, only the 50° parts have been modified, but if demand exists, the rest of the parts will be revised accordingly. Update: 30° parts have been added to the collection. Slots have been incorporated into the 30° angle part to facilitate the addition of hex-nuts. Holes have been drilled into both the 30° angle and roll-mounts to reinforce the ball-bearing shafts with nuts and bolts.
