Yagi brackets for 1/4" aluminum elements to mount to round booms

I initially used the scad files at the thingiverse link to generate brackets close to the size I needed for the aluminum element diameter, and round boom diameter to clamp them too.  If you want to do this just download openscad and do it in there, as the app in thingiverse to do it is broken. However after doing that I further sized both holes to have a better fit around the parts I used.

The 70cm brackets are for ¼" diameter aluminum elements, attached to a ¾" diameter boom.

The 70cm brackets are all cut down to be less wide as to better fit elements closer together on the boom.

The 2M brackets are for ¼" diameter aluminum elements, attached to a 1" diameter boom.

The “clamp” files are for the directors and reflectors.

The “dipole” files are for attaching a dipole. They include 3 parts, the base of the clamp, the top, and a fairly waterproof cover to go over the connections between the so-239 connector and the driven elements of the dipole. These require threaded heatset inserts for attaching the cover to the top. These are standard voron heatset threaded inserts OD5mm L4mm. You will of course need additional bolts, washers, lock washers, nuts, etc to attach the SO-239 connector to the top. I used M3 BHCS of various sizes.

I've included not only the stl files, but both f3d files as well as step files in case you want to remix and modify for different size elements and booms.

I sized everything for ASA. You may need to adjust scale for PLA or PETG.

The bolts to attach the brackets to the boom are M4x30 BCHS and M4 nuts. To attach the elements to the brackets are M4x12 BHCS and M4 nuts, except for the 70cm dipole bracket which needs m4x16 BHCS and m4 nuts. 

To attach the cover to the top are m3x5 or m3x6 BHCS.

Update Added STL: yagi 70cm clamp with wiretie v2.stl which has convient spot to attach a wiretie to hold your coax cable to side of the bracket.
