Coil stiffeners

[Slimpickins]

Any recommendations for a coil ear stiffener for an Equinox 12”x15” coil? I don’t think Kellyco offers any. Are any of them solid rather than hollow construction.
Thanks

I got mine from a local guy who makes them. He was on Ebay the last time I checked. I believe he lives in El Cajon, Ca.

or post / ask if anyone has STL file for one.

The ones I have found that 3-D printed are hollow. Therefore, I cut the bottom of the side tabs and injected an epoxy into them. Mine are very stiff now and have been working well for me.
