This Magwell Flare fits Aero Precision M4E1 AR15 Lower with slip-on fit and retention features wrapped around rear.
Fit is tight; if printer oversizes part then filing angled contact surfaces should be workable. The rear retention features can be reduced for ease of install but will more easily slide off receiver if impacted on rear end.
Print in PolyMaker PolyLite PLA PRO. Other materials may work but the flex and strength of PLA PRO is well suited to this part.
Will not fit standard milspec receivers or close derivatives, Aero Precision USA M4E1 is a flared receiver. Will not fit Aero Precision X15 receiver (use mil-spec magwell flare).
Reported to fit M4E1 Pro receiver with some minor front-back play. Consider trying small fractional scaling and see if it fits better.
