Gridfinity Generic DevBoard Holder

prusaprinters

This holder allows to store development boards with pins mounted on the bottom in Zack Freedman's Gridfinity system. As such boards come in various sizes (e.g. different ESP8266 or ESP32 boards, Raspberry Pi Pico, Arduino Nano, …), the surface of this holder just mimics a breadboard by providing a 0.1" grid. The holder as such is stackable, so that you can put multiple DevBoard holders on top of each other. On the bottom, the model uses half-sized profiles, which allows stacking it on top of smaller Gridfinity bins, which you might use to store your electronic components. There are multiple sizes of the holder available, either in 2 or 3 height units. The 2 unit one will probably only take very flat boards without any larger components on the top or become unstackable.Print SettingsLike with most Gridfinity bins:Layer height of 0.2 or 0.3mm, at least for the bottom and top profiles don't go higher than thatYou can reduce material consumption by reducing perimeters and infillAlso, after slicing, check the grid in the box if it has been sliced without artifacts (like missing separation lines). For Prusa Slicer, this should work without issues for versions >2.5 with the Arachne algorithm being chosen.For most common nozzle sizes, the edges of the grid should be sliced as a single perimeter. I haven't found a way yet to convince the slicer to print them in an efficient order – if you have an idea, please let me know :) If you need more sizes, please just leave a comment.
