Because I beleive this frame is a great base from which all sorts of fun/cool edits can spawn, I left it as a blank slate - 
it's ready for whatever wackyness and fun you want to bring to it.

To account for this (and to help get these edits more visibility), I propose this solution: 
I will maintain a a collection of remixes in the "Remixes" folder that will contain all the fun/cool mods everyone comes up with.

For simple remixes, Once you have designed, printed, and tested, you can send me (Ivan on Deterrence Dispensed Rocketchat) a .zip file that contains: STEP files, STL files, 
Renders (pictures of the real gun preferred, since I ask that you actually print and test everything), as well as a basic README - 
this readme only needs to describe the name of the design, the designer, and any other tidbits about it.

I'll review your submission, and if everything is up to snuff (all the files I've asked for are present and it's been tested),
I'll get it added to a collection of these remixes found here:

For remixes that add parts, change function, and require anything that the main build documentation doesn't cover, I ask that you provide all the things mentioned for the simple remix,
as well as pictures/text based instructions on how to properly assemble/use what it is you come up with (so that it is as accessible and the canonical package is).

Things that aren't quite remixes (more like add-ons or doo-dads that are compatible with or designed around the DDxx.2 family), such as printable sights, rail accessories, etc,
can be submitted the same was as I've described for simple remixes (unless they need special instructions/aren't completely straightforward, in which case they should be like a complex remix.

For questions about this system, you can contact me (Ivan on Deterrence Dispensed Rocketchat).
