This is a remix of Chris Carter's original design found at https://www.printables.com/model/1515825-omp-m1-evo-open-front-canopy.

I simply chopped a little off of Chris's original design to facilitate ease of printing along with battery removal.

This open nose design allows for battery change without canopy removal. You can make a tiny extension cable that stays connected to the flight board to make plugging and unplugging easier or just look in the side window to push the battery connector in like I do. I use a small plastic trim tool for scooting the battery out of the tight compartment, so I don't have to yank on the battery leads.

I uploaded the canopy in the orientation (flat on its nose) found to give the best possible quality with the least number of supports.
