Noncommercial use only, please. This model contains custom supports that are not shown in the renders. To build it correctly, ensure it's rotated on your plate with the large opening at the bottom. If you're interested in an RMR cut cover plate, check out my other designs. 5/19/2019: I added a version without finger grooves. 7/28/2019: See my new HSLD version here: https://www.thingiverse.com/thing:3776968 This is a work-in-progress model of a Polymer80 flared magwell, tested only on a PF940v2. If you try it with another model from their line, please let me know if it works. I've tested this design with Magpul and ETS 17rd magazines to ensure drop-free function. However, I haven't tested it with stock Glock magazines. As long as the baseplate is smaller than the Magpul mags, they should work. I added finger grooves so you can grab the baseplate to clear a malfunction. Almost included is a version without grooves. This model doesn't fit exactly flush at the back of the grip; that's still a part in progress. Print this design with as tough filament as possible and with maximum infill. I use a bit of brim to help keep warping down. PLA will likely crack easily if you're a real operator who kicks doors. I've used PETG and polycarbonate so far, and the frame is nylon, probably with glass fiber reinforcement. The weakest part of this model is the grip plug. If you torque it too hard, you can delaminate it, but that's never happened to me with my current versions of this design. If you print this in ABS/PETG or stronger materials and manage to break it while it's installed, I'll be impressed. It's a click fit, and once on, it won't move easily. To install it, put the front of the frame in first, then lever the back on. Once it's on, check the magwell to make sure it's flush against the frame all around. The easiest way to remove it is by flipping the frame upside down and backwards, then levering the back of the magwell off with your thumbs. I use a bit of brim to help keep warping down.
