Circuit Playground Express Snap Fit Mount with Alligator Clip Cutouts

thingiverse

This is a remix of the [Circuit Playground Express Snap Fit Mount](https://www.thingiverse.com/thing:3878226) with several key changes: * Alligator clips are allowed on the Circuit Playground Express thanks to cutouts. * The external edges wrap around the board. * A wider internal "ring" supports the board's edges. * Reduced to a single alignment pin - one of the three ground points is used for alignment and cannot have an alligator lead clipped to it (two other ground points are available). To insert the board: * Insert the board slightly tilted so that the alignment pin goes through a hole. * Apply gentle outward pressure on the opposite side as you press the board in. * It should snap into place. To remove the board: * Locate the clip on the side of the board opposite the alignment pin. * Press the bottom side of the board near the clip to apply gentle outward pressure until the edge of the board pops free. * Once one edge is released, you can lift the board out of the case. Additional notes: * The Fusion 360 file and STL file are included. Feel free to improve on this version. * I'm new to CAD and Fusion 360, so expect problems and inefficiencies in my Fusion 360 file. * The snap fit clips on this remix are narrower than the original and may break depending on your print material and quality. It's working for me using Prusament PETG, but PLA might be more brittle. I'd like to thank Noe Ruiz at Adafruit for sharing his design process and techniques in his video at https://youtu.be/GlMo6IWF6CY. His video is embedded above, but it's not my work - I'm just grateful to have come across his videos and expertise.
