I have a great set of lights, however I have a HP Velotechnik Recumbent Tricyle, which means I don't have the traditional handlebars, or seat post on which to mount my lights. I needed to be able to mount the front on the main boom, and the rear (see other model) to a horizontal stay.
There is a threaded boss on the from boom, so the mount is attached by a single cap-headed Allen (hex) bolt.
Printing on it's side keeps the supports from interfering with the bolt-hole, and improves strength.
I hope this helps. Please leave a like if it does, and post any makes or remixes.
