"As a 3d printing nerd, one doesn't buy plastic things one can design and make" 

The only plastic I buy now comes on spools. So I hit up Fusion 360 and made this little guy. 

THE NEED++++
Was getting hangups on my magazine changes on the lip on the back of the inside of the magazine well. This little piece of plastic fixed that. 

I have grip tape on my guns, so the little hole on the grip is covered.  This plug has a hole designed into the print to place a tool to eject the printed piece. 

Hope you all enjoy this design as much as I due. If you all want any changes in the design, let me know.

PRINTING++++++

Print in the orientation I have on the photo for a great exposed finish. You will need supports.

Please give me any feedback to make it better.
