3D

‎​I printed off a modified model that addressed some issues and also added the right-end piece for the first time.

The back got a little bit deeper to accommodate a deeper screw hole. While the depth seems about right now, the length of the channel is too short so I can see the model popping off. I’m diving into constraints in Fusion again to try to fix this.

For the right-end piece, I cut a hole for USB-C and then an interior channel for the rest of the board to sit in, as it juts out. I also originally had an interior block in the channel to try to keep the board from moving around, but it seemed to be in the way so I carved it out… but I put all of this in the completely wrong place, so I have to make adjustments and print again anyway.

‎​I tried printing off an end piece after I made some minor adjustments to the mounting holes but they weren’t enough.

I also learned that the mounting holes aren’t aligned properly on the end piece, which makes sense since I’ve only printed them once.

The side piece is also cut for the wrong side 🙃

‎​It turns out I had modified the peg depth, so this new model sits flush with the matrices.

The matrices taper from the front to the back, so my initial measurements were incorrect since I measured the back and didn’t account for how much space the front takes up went sitting next to each other, so I added a little bit of extra space. I also tried tapering the models edges to match. It’s not perfect, but I think it’s close enough!

I worked on this for about a week prior but didn't make a project. A lot of it was working on software, which now works pretty well. Then, I started modeling a backplate since the LED matrices have very convenient hole patterns around their perimeter that I figured I could hook into.

After some back-and-forth, I got the hole pattern correct in Fusion 360 and printed out a central plate that holds the two matrices together. There are some adjustments that need to be made regarding peg length and angle but it works well.
