Hey guys I had some free time so I decided to model a M203 stand alone since none of the design available online matched my tastes. Download the files, buckle up and follow this thread to get an awesome M203 Stand alone launcher.
Ofc the eotech and m203 are not included in this project.
I have to be honest this is not the easiest piece to print, but it requires no threaded holes, little support and can be printed on pretty much every printer.
To do so, I put 2 pockets for M5 nuts that are needed to connect all 4 pieces together. If you add glue it becomes a whole piece.
To put the nuts into the pockets correctly you need to:
In the STL folder you can find factory files for all the pieces, with 3 process preset for barrell + slitte.stl so it's super easy. This way I also change the infill during the print.
The other files can be printed normally. I suggest not to use support for the rails.
Barrel + slitte.stl
Layer: 0.2
Shell: 3
Infill: 30%
Material: PLA -ASA - PETG (ABS risk delamination be careful)
Supports: no
Other pieces
Layer: 0.2
Shell: 3
Infill: 20%
Material: PLA -ASA - PETG (ABS risk delamination be careful)
Supports: Only for the grip and barrel 3
For the assembly you'll need
Assembly
It's kinda easy. Just apply glue and screw the screws. Or follow the pictures.
Things to fix
Again I'm in Slovakia so at the moment I cannot access my airsoft equipment. It would be nice to have a M4 compatible Grip.
I modeled this pretty much copying the G&P launcher so the proportion should be correct but looking at the picture it looks like the grip it's a bit too high. Maybe also the G&P version has this issue. Feel free to modify the CAD and update this project

- Fully printable on 180x180x180mm plate
Printing procedure
I have to be honest this is not the easiest piece to print, but it requires no threaded holes, little support and can be printed on pretty much every printer.
To do so, I put 2 pockets for M5 nuts that are needed to connect all 4 pieces together. If you add glue it becomes a whole piece.
To put the nuts into the pockets correctly you need to:
- Print Barrel + slitte.stl alone
- Make sure the side with "down" carved in it is indeed down
- Insert pauses in the gcode at 20,50mm and 155mm
- Print the piece and insert the nuts during the pause
In the STL folder you can find factory files for all the pieces, with 3 process preset for barrell + slitte.stl so it's super easy. This way I also change the infill during the print.
The other files can be printed normally. I suggest not to use support for the rails.

Things you need
For the assembly you'll need
- 1pz M5x50 (or bigger, recommended ISO 4762, aka cylindrical head with hexagonal pocket)
- 1pz M5x30 (or bigger, recommended ISO 7046, aka Phillips/cross screw, otherwise you risk to trigger the granades)
- 2x M5 nut
- Gorilla glue or abs juice if you're using ABS
- M6x40 or less for the grenade holder
