This system allows you to temporarily setup electronics or other devices on an extensible modular base platform:
The base is this 12x12cm big and 1cm high base platform:
The primary base platform is 12x12cm big, 1cm high and has a 2x2cm grid for clipping in all sorts of stuff, such as:
- Bread boards
- Electronics modules such as:
- Arduino Uno / Nano
- Raspberry Pi 4
- Raspberry Pi Pico
The system is extensible as with the generic clip design you can make your own models to clip into the board. A clip looks like this:
The clips hold well in the holes, you will need either strong fingers or pliers to pull them out again. The clip arms will be printed with 3 0.4mm thick walls, which provide enough flexibility while also holding tight. The clips also provide a rotational stability.
The advantage of this system that connects holes is also, that if you damage a clip, you can reprint them quickly.
There is a whole palette for holdes/clip holders to choose from in the clip.blend

I was inspired by:
- 3D Printing Professor's PrintABlok
- While I like this approach and it's design is superior to mine, I wanted something a bit more compact and less bulky.

- Pin Connectors V2
- I like the simplicity of this design, but these round connectors would make the MakerGrid too wobbly if not connected by at least two pins. My grid clips are rectangular and already provide some stability if you just plug in a single one.

- Type D:
- Build Cubes in sizes 1x1, 3x1, 7x1, 11x1, 15x1 offer a way to extend
the maker grid into 3 dimensions.
- Also with a slim variant that has the "_s" as postfix.
- And a base extension variant, that can be plugged to the side of the MakerGrid bases with an "_x" postfix.

Basically you can print it in any way you like, but I recommend following settings for printing:
- 0.4mm nozzle
- 0.3mm layer height
- For the clips themself I recommend a wall thickness of 1.6mm:
For the other parts even 0.8mm works fine.
The rest you can vary to your likings. I printed it in PLA. Not tried it in PETG or ABS/ASA yet, but should be even better for the clips (due to better flexibility).
