Slotted Bike Rack light bracket

I needed to mount 2 lights on my new recumbent tadpole trike. The brackets that came with the lights were meant for handlebars or seat post, neither worked with my trike at all. Its a standard square slot you can mount the light either direction.

Designed to be used with 2 3mm x 20mm machine thread bolts and 2 square nuts that are held in place by the body of the bracket.

Updates:
1.0 Base model
1.1 Made slot deeper and added a small nub internally to the slot. I lost a light on a ride last night. Ended up finding it but warranted a change to the design
1.2 Wider mounting points
1.3 Made deeper slot and extended the length to prevent distortion and cracking
