12mm Rod/ Shaft Support Block, for OpenBeam

this is a 12mm support block with two tiedown openings on the shaft clamp, the holes are designed for a M3 bolt and Nut, both sides are countersunk.
the part is 15mm wide so fits perfect on OpenBeam extrusion as i have designed this for a 3d printer im building using Open Beam, i will be uploading a lot of parts shortly now that i know i can design and print with good quality.
In reality this fits anything that can be mounted to with M3 bolts, the surface mounts are all M3 holes Countersunk
