Ordering Splitflap v0.5/v0.6
The instructions below will walk you through ordering all the parts (excluding common tools) needed to build a splitflap v0.5/v0.6 display with 4 modules.

Please leave inline comments below if you have any questions or come across anything that looks incorrect!
If you are interested in building a display with more than 4 modules, please see the notes at the bottom of this document about how the controller PCBs can be chained together for up to 12 modules controlled by a single Arduino Uno.
If you have any questions, please feel free to reach out to me (scottbez1 at gmail or just mention me @Scott B in a comment on this doc). Or, , to discuss or ask questions from the wider split-flap community! (it’s still new, so it may be a bit quiet, but don’t be shy!)
Order laser-cut parts
There are many places you can get laser-cut parts, but I’ve personally used Ponoko and Elecrow for ordering shipped to the US with an easy online-only process. I’ve been using Ponoko for several years and they offer a lot of different material options and good quality, but recently I’ve found Elecrow’s laser-cutting service, which can be significantly cheaper with good quality (though very limited material options).
Note: Ponoko has rebuilt their website and changed the ordering process since these instructions were first written. I’ve included links to both the old SVG files (which probably aren’t useful anymore, but kept for posterity) as well as some newly generated SVG files that should work better in theory, but I have not personally validated them. If you use the new files, please share your findings in (join ) or leave a comment here - it’s hard for me to keep up with changes from Ponoko, so feedback from others is critical to keeping these instructions up to date.
- New (untested) files
- 1 module
- 3mm MDF: https://github.com/scottbez1/splitflap/releases/download/v0.6/v0.6_laser_vector_ponoko_mdf_1x.svg [178.6 x 173.33 mm]
- 3mm Acrylic: https://github.com/scottbez1/splitflap/releases/download/v0.6/v0.6_laser_vector_ponoko_acrylic_0.08kerf_1x.svg [178.42 x 172.97]
- 4 modules
- 3mm MDF: https://github.com/scottbez1/splitflap/releases/download/v0.6/v0.6_laser_vector_ponoko_mdf_4x.svg [357.2 x 346.66 mm]
- 3mm Acrylic: https://github.com/scottbez1/splitflap/releases/download/v0.6/v0.6_laser_vector_ponoko_acrylic_0.08kerf_4x.svg [356.84 x 345.94 mm]
- (Developer note: for legacy reasons, both MDF and Acrylic files are generated with design thickness = 3.2)
- Old files
- These use Ponoko’s old “P2” template, and their new website seems to get the dimensions wrong when uploading them. Please beware of the dimensions if you use these on the new website.
- 4 modules, 3mm Acrylic:https://github.com/scottbez1/splitflap/releases/download/v0.5/LEGACY_laser_vector_ponoko_4x_p2_ACRYLIC.svg (also, see the important note below about Matte 1-Side acrylic)
- Go to and sign up for an account.
- the SVG file from above. Confirm the dimensions match the values above, and check that blue lines are set for “Cutting” and black fill is set for “Area Engraving” (or turn this off)
- Select a material - or are recommended — choose 3.0mm (0.12 inches) thickness. Make sure to check the material’s maximum size against the dimensions provided next to the file links above; some materials may be too small to order the 4x versions.
Important note if using Matte 1-Side acrylic: make sure to put a special request in the shipping instructions to engrave on the glossy side! This will ensure that the nice matte finish ends up on the outside of the design. If you are not able to do this (I haven’t ordered matte acrylic since the website redesign, and the website no longer mentions this special request option), you should mirror the designs before uploading and remove the engraving.
Elecrow will cut 5 copies of the design per order from “wood” (unspecified type), for $14.55 + shipping. I think you’d be hard-pressed to find a cheaper deal (but let me know if you do!).
