Remix of previous blocks that I've uploaded.

These have 5/8"(16mm) lands for standard ¼" washers.

Also trimmed some surfaces to reduce plastic.

3 axis blocks can be mirrored for different orientation.

Rod Rollers as seen on the rotary to linear drive are also available. They use 1-½" long ¼" bolts, and 4.5mm BB shot for ball bearings. The caps are standard ¼" washers, and the assembly keeps together with ¼" nylon lock-nuts.
