Default GT1 frame with lots of extra steel

My batwings or bottom bracket support is made using a jigsaw with a fine steel blade, angle grinder, bench grinder and hand files.
I traced the outline and went slowly going forward, backing off a little, all the way around.

I had the help of cutting lube to help the blade around the curve.
