This is a remix, I changed the ergonomics of the handle and added holes and clamps for securing the bands. It is set up for 1" 12-24 machine screws to bolt the bands in place.

It is set for TTF shooting, but could be modded for OTF

One of the clamps is setup for a fiber optic, it requires a bit of fitting to get the fiber to thread correctly, I used crazy glue to hold it in place, a larger fiber optic would be better, but this i what I had on hand. And for what its worth it works out quite well, hitting cans at 11yrds is very easy.
