I needed a small bracket to mount the end of some Unistrut/Superstrut to the wall to brace a telecom rack. I didn't have enough room on the wall to use a traditional ladder rack and wall bracket for bracing, but a Unistrut fit the bill.

After looking around, I didn't see anything that did exactly what I needed, so I used Heflin's "Unistrut Superstrut end cap" to align the strut on the mount, and added a bracket to it to support the Unistrut. It features a decent amount of fillets on corners to help reinforce the weak points of the print. I am printing it in ABS just for some extra durability, but the test print I did in PLA Professional was probably strong enough to do the job.

To use: screw or bolt to the wall using one of the two mounting positions. Get the Unistrut in place and mounted to the other end, whatever that may be. Get it squared up nicely and use the other mounting position to secure it. Run a bolt and washer through the Unistrut and through the mount, then use another washer and nut to secure it.
