The Buildable Stick System

Files for 3D printing an arcade stick.

Originally an attempt to make a couple customized STL files for the OpenStickCommunity Fightstick Case, 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)
  • 4 M3 8mm hex bolts to secure the PCB to a panel
• Per frame and plate combo:
  • 4 40mm M4 hex brass standoffs (or equivalent)
  • 8 12-16mm M4 countersunk hex bolts
• Per frame connection point:
  • 8 16mm M4 bolts
  • 8 M4 flange nuts
• For a lever:
  • 4 12-16mm M4 countersunk hex bolts
  • 4 M4 flange nuts
• For Neutrik D connections:
  • 2 10mm M3 hex bolts
  • 2 M3 flange nuts
• Buttons and levers as desired
• Wiring as required

Rough Costs

This is a rough estimate of the cost to produce one of these sticks, assuming a usual 2-frame design and layout. Filament masses from Bambu Studio estimates, using Bambu PLA Basic.

• Left and right frame: $7.08 USD (141.84g each, as of 2023-09-12)
• Left and right top panels: ~$6.74 USD (~135g each, as of 2023-09-12)
• Left and right bottom panels: $5.90 USD (118.16g each, as of 2023-09-12)
• Miscellaneous mounting plates, decorative plates, etc.: ~$1.00 USD (~40g, as of 2023-09-12)
• 8 16mm M4 bolts to connect the frames: $0.72 USD (you can get a pack of 100 on Amazon for $9, as of 2023-09-12)
• 8 M4 flange nuts to connect the frames: $0.68 USD (you can get a pack of 100 on Amazon for $8.50, as of 2023-09-12)
• 4 10mm M3 bolts to connect Neutrik D plates to frames: $0.40 USD (you can get a pack of 100 on Amazon for $10, as of 2023-09-12)
• 4 M3 flange nuts to connect Neutrik D plates to frames: $0.34 USD (you can get a pack of 100 on Amazon for $8.50, as of 2023-09-12)
• 8 40mm M4 spacers to connect panels to frames: $2.40 USD (you can get a pack of 10 on AliExpress for $3, as of 2023-09-12)
  • You could 3D print these too, but you're probably better off with brass ones as they give some weight to the stick anyway
  • You can also use a shorter length with longer bolts, or combine multiple spacers, if either of those yield better prices
• 8 16mm M4 bolts to connect top plates to frames: $0.72 USD (you can get a pack of 100 on Amazon for $9, as of
• 8 12mm M4 bolts to connect bottom plates to frames: $0.72 USD (you can get a pack of 100 on Amazon for $9, as of 2023-09-12)
  • You may be tempted to use 16mm M4 bolts for both the top and bottom, but the spacers I have aren't threaded all the way through the shaft, and 16mm bolts won't make it all the way on the bottom panel, but do on the top panel (which is 5mm thicker); be careful I guess

With an enclosure coming in around $26, depending on your choices --- say, ~$30 for TheTrain's RP2040 Advanced Breakout Board, ~$60 for Sanwa buttons and a lever, and ~$20 for miscellaneous connectors and wiring --- you can put a full-featured controller with an open source foundation together for around $135.

Miscellany

See the /docs/ directory for more thoughts too scattered for this document.

Issues and Limitations

This is a living repository, and as such, there are likely issues with the objects, known or otherwise. 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.
