Frame for 64x32 LED Matrix 4mm Pitch with adafruit MatrixPortal (adabox 016)

thingiverse

This is sort of a remix, but I coded it from scratch in openscad using the original for inspiration and a few dimensions. It is slightly bigger to fit the diffuser panel and has fewer holes in the back. To get dimensions from an STL file, I used this free tool on windows: https://www.3d-tool.com/downloads/setup_3dtool_freeviewer.exe This frame is for a 32x64 4mm dot pitch panel with a diffuser panel. It's fits the panel included in Adafruit AdaBox 16. adabox16: https://www.adafruit.com/product/4812 https://learn.adafruit.com/adabox016 panel: https://www.adafruit.com/product/2278 diffuser: https://www.adafruit.com/product/4749 See the adafruit pages for more details. My wife loves the moon phase clock (also called the werewolf clock) https://learn.adafruit.com/moon-phase-clock-for-adafruit-matrixportal The matrix panel sits flush with the sides with the diffuser attached. Originally I only added mounting holes for a vertical orientation for my usage, but the uploaded files include mounting holes for 3 orientations: vertical with cpu at bottom, and horizontal with cpu on the right or left. The vertical uses a single keyhole and the horizontal orientation uses two keyholes spaced 6 inches apart. The finished frame is too big for most printers, including my Prusa i3 Mk3S+, so like the original, I split it into 2 pieces that can be printed vertically without supports. Because I plan on mounting this vertically, I call the 2 pieces top and bottom, instead of left and right like the original. The "bottom" is the side with a slot for the matrix portal card. I did not add any holes for viewing the leds on the back of the device, but this would be an easy modification in the openscad source. Use M3 screws to attach to the panel. The tabs in the middle are staggered and those screws will go through a tab from each half. I used M3 x 8mm hex socket bolts but almost any M3 bolt would work. I am a big fan of openscad (https://openscad.org), which I used for this project. The source file is included with no restrictions.
