This is inspired by Gridfinity Generic DevBoard Holder. I didn't need the half grid base, which slows printing time, and the tallest bin there is 3 Gridfinity units, which doesn't work for boards that have stacking headers, or breakout boards with taller components.

This is a customizable alternative, using Gridfinity Rebuilt in OpenSCAD as a starting point. The rendered STLs I've uploaded are all 4 units high, and have no magnets on their bases.

Print Settings

Use your normal Gridfinity settings, but be sure to select the Arachne wall generator, if it isn't default in your slicer. With the thin walls and tight spacing, this gives the best quality, while saving time too.

To Customize

• Download and extract “gridfinity-rebuilt-openscad-devboard-bin.zip”
• Open the file “devboard_bin.scad” with OpenSCAD
• Edit to suit your needs
• Render and export STL

For best performance, use the newest development build of OpenSCAD you can get, with Preferences > Advanced > 3D Rendering > Backend set to "Manifold (new/fast)". The preview will probably fail on larger bins, but render is extremely fast.

EDIT 24/12/07:

• Added all pre-rendered sizes to the .3mf file, on separate beds
• Added complete OpenSCAD project as a .zip file and updated customize instructions

EDIT 26/03/16:

• Added more pre-rendered sizes
• Added inlined version of openscad file for use with customizer
