like this...??? I had this made from the file I posted above, to my knowledge it was designed by someone at Magpul (the owner)… It cost me 100.00 to have it made on an HP professional 3D printer, it's made of reinforced nylon... The insert is a genuine Magpul and fits perfectly... It was worth the money to me, I have large hands and it was produced in a couple days for me... I inquired about having a quantity made, I could get the price down, but figured others can take the file and have it made...
