wanted one of these for a promag to keep the feed lips from spreading when stored loaded. just trimmed off the ridges for the aluminum mag and it fits snug and does what I was looking for. also works on amend2 mags.

added a v2 that stands 5mm taller for even better fit

printed in petg since it has some flexibility. set top and bottom layers so that the top is all solid with no infill- that resulted in a good top surface- often with petg I have a hard time when using infill getting the top to not have artifacts from the infill.
