The case is designed to house all of the electronics. I designed the two parts to snap fit together so there’s no need for additional hardware. The two pieces lock together making a tightly secured enclosure. The PCBs are secured to the bottom cover using M2.5 (.45 x 5mm) machine screws.
Choose your preferred material, PLA is what I used. Composite wood PLA and CoffeePLA might look more interesting. You can use strong materials such as ABS, Nylon, PETG, etc. just be aware the tolerance may vary when using materials other than PLA.
Size & Dimension
This drawling shows the dimensions of various features. Here's a list of some of the important things.
- Case – 84mm x 84mm x 12.5mm
- Acrylic Slot – 50.4mm x 6.8mm x 5.5mm
If you'd like to make adjustments to the case, you can download the Fusion 360 Archive for free and modify the model using your preferred CAD modeling program (STEP, IGHS, Solidworks, STLs, etc.). The design is parametrically driven with User Parameters, so it's very really update values such as the tolerances, thickness, height and number of buttons. The design will automatically update and scale depending on the values. Watch my "Layer by Layer" tutorials to get an in-depth walkthrough of the model.
