# Bullet System Stick
Files for making an arcade stick.
Files for 3D printing an arcade stick.
These files are suitable for previewing and rendering in OpenSCAD.
Originally an attempt to make a couple customized STL files for the [OpenStickCommunity Fightstick
Case](https://github.com/OpenStickCommunity/Hardware/tree/main/Fightstick%20Case), the changes ballooned to fit my
design and became incompatible with that project's components. This should be considered a different project with some
similar DNA, but to stress again, it could not have been done without that project as a guide star. See **Attribution**.
## Designing
No particular arcade stick design is prescribed by this project, instead, SCAD files are provided to choose desired
component objects or create new ones. The OpenSCAD language is essentially a functional programming language, making it
it easy to reuse, alter, and compose objects. If you do not see the object you would like, you can likely create it by
starting with an existing object and constructing what you'd like with new or existing components.
## Printing
These items all fit on a 256mm^2 print bed; I use a Bambu Lab P1P based on what I've learned from the
OpenStickCommunity. Standard settings seem sufficiently sturdy for my purposes, though the slicer has done a couple
weird things, in my experience.
## Assembling
What you'll need beyond these objects:
* An arcade stick board (I recommend [TheTrain's RP2040 Advanced Breakout
Board](https://github.com/OpenStickCommunity/Hardware/tree/main/RP2040%20Advanced%20Breakout%20Board))
* 4 M3 8mm hex bolts to secure the PCB to a panel
* Per frame and plate combo:
* 4 40mm M4 hex brass standoffs
* 8 12-16mm M4 countersunk hex bolts
* Per frame connection point:
* 8 25mm M4 bolts
* 8 M4 flange nuts
* For a lever:
* 4 12-16mm M4 countersunk hex bolts
* 4 M4 flange nuts
* Buttons and levers as desired
* Wiring as required
### Issues and Limitations
This is a living repository, and as such, there are likely issues with the objects, known or otherwise. Be aware:
* The top panel is 5mm tall and doesn't have an inset; snap-in buttons likely do not fit.
* A composition error made the frame 5mm shorter than intended and wasn't noticed until I printed everything:
* Some levers don't have enough clearance in the case.
* Buttons with traditional quick connects are a *very* tight fit, you will probably need to bend pins.
* The PCB mount position was very tight on the buttons panel; it will probably have to be moved.
* Support for the top plate was removed from the frame due to overhang issues, and now the top plate can bow slightly
with pressure; a new solution needs to be found.
These issues may be fixed in the future; see `TODO.md` for details.
## Development and Contributing
Improvements, variants, new layouts, novel ideas, and etc. are all welcome.
These files are suitable for previewing and rendering in OpenSCAD. They may also work in FreeCAD and perhaps other
software, but they are developed in OpenSCAD, so YMMV otherwise.
