Like its predecessors, this Tinkertoy-compatible bearing system uses ten 4.5mm BB’s to provide smoother rotation than the stock wheels included with a Tinkertoy set.

The center bore is *just* a little loose on a Tinkertoy rod (not known for their precision diameters in the first place) so if you really need the bearing to stick fast I recommend using a little piece of painters’ tape around the rod.

This is a remix of TheRooster’s Printable 608 Ball Bearing and uck’s Tinkertoy to Lincoln Logs (uck-07f06m) adapter.

What do you think?
