Firearms, not politics. This welcome message was crafted by the WF&GCI community moderators to help you out when you join online community, or if you are intrested in learning more about us and our firearms.


Welcome to WeightForward & GunCADIdeas - 3D printed firearms dev group

This is a chill group for firearms and 3D printing hobbyists. We focus on designing guns for the hobby community. Home of the Derwood Designs, Mussy Designs, and many other developers. The collective has released popular firearms designs like the King Cobra9, MOD9 series, G22 Grizzly XL in collab pilothobbies, WTF-9 series, PPDW9 Series by Wildcat_a, Romulan Charger by Wildcat_a, and many more designs that are listed below.


Matrix is a live chat room that we use to communicate. We have emmigrated to it from Keybase after they banned us. Since their was no chance of Discord letting us on in any capacity, we made due with the best software we have access to, and that was Matrix.

We highly recomend you use the Element phone app and/or PC program to connect to the Matrix server we are on.

OPSEC and PERSEC in the Online Community

5 Safety Guidelines Before Posting in the Team: Your OPSEC or PERSEC could be in danger if you don’t act responsibly.

  1. Post Safety Tip #1 Personally Identifiable Information. Do NOT share personally identifiable information. (Ex. name, address, place of work, personal social media accounts, personal emails, schools attended, previous employers, etc…)

  2. Post Safety TIP #2 Oversharing. Do NOT share the people or places from your personal life. (Ex. usernames of other accounts you have, places you frequently visit, events/conventions that you have/will attend, popular local places in your town/city, your local polticians, government leaders, sheriff, etc…)

  3. Posting Safety Tip #3 Self-Incrimination. Do NOT make statements or post pictures that break the laws in your country or states [i.e. Australia, UK, New York, New Jersey, California, etc..].

  4. Photo Safety #1 Identifying Information in Photos. When posting a picture, beware to not show identifying information, and do NOT show your finger tips, try to only show the firearm and the background. It’s easy to focus on what you’re taking a picture of in the foreground and forget to remove any identifying information from the background. (Ex: shipping labels on boxes, mail, work and school ID, family pictures, license plate, school and work logos, symbols, signs, and/or banners)

  5. Photo Safety #2: Metadata found in Exifdata Element does NOT remove exifdata/metadata from your images when you upload them to Element, meaning it is not safe to upload photos unless the exifdata is removed. The significance of metadata is it can tell someone anything from your name, brand of phone or computer, the OS of your computer or phone, the timezone you are in, or the exact GPS cordinates of the place the picture was taken.

    Removing Exifdata before posting:

    • Windows Computer: Open the image in Paint, click the Select tool, press CTRL+A, press CTRL+C, open up a new Paint window, and then press CTRL+V and then save as .png.

    • Phone: Note that cameras are set to automatically write exifdata to photos. Therefore its is recomended you turn off the location setting in the Camera app.

      1. The Element app has a built in camera that removes exifdata, making it safe for the photo to be uploaded.
      2. Screenshots, do not save exifdata to images. Take a screenshot of the photo you took while it is full screen on your device.
      3. Use a 3rd party app to scramble or remove the exifdata from your photos.
