My version of a breadboard holder for the amazing gridfinity system, as I wanted to use gridfinity to organise my whole electronics prototyping space. 

This bin has space for a 830-hole breadboard (JUST fits..), and a range of bits in a storage trough alongside. I've added 4x M3 mounting holes (threaded inserts diameter for the first 5 mm, then thread cut into PLA for the rest). I use these to hold random additional boards (eg. a LCD screen) that are hole-mounted rather than pin. The trough does just fit a PP3 9v battery for powering the breadboard (or a whole range of lipo options of course). 

I've hollowed out the space under the breadboard - mostly to lightweight it - but it might be useful storage sometime (for the power bank?). The two dips in the divider are so that you can get the board back out again. 

The bin is stackable when empty - but I did go with the decision to mount the breadboard high in the bin when in use - so that things could stick out of the ends and sides (as in the photo). It's a reasonably snug fit - but I didn't make it tight - so a bit of bluetack will add some stick as needed (eg. in my next project, where I add wheels to this setup!)

I hope you enjoy this model. 

Kudos again to @scheff for the blank bins, and obviously Zack Freedman for the gridfinity movement.. 

Sub-component stuff: 

The electronics in the photo are part of a kit I bought for the Raspberry Pi Pico - which I would recommend - it comes with the breadboard, pico, power supply, jumper wires, LCD and a whole range of other bits to prototype some nice projects. [https://amzn.to/4gSPci6](https://amzn.to/4gSPci6)

The threaded insert set I use can be obtained from Amazon here: [https://amzn.to/3BFAJas,](https://amzn.to/3BFAJas,) the inserts themselves are here: [https://amzn.to/3DFTKtO,](https://amzn.to/3DFTKtO,) the standoffs here: [https://amzn.to/4gGzdUH](https://amzn.to/4gGzdUH) and these are the magnets I use for all my gridfinity stuff: [https://amzn.to/3DFTKtO.](https://amzn.to/3DFTKtO.)  

(Note: These are associate links, which means that they don't cost you any more, but I get a small cut if you purchase via these links. This isn't a big money-spinner, but I find it so useful to have sub-components linked in models that I download - so I know I'm getting exactly the right bits without much research, and it helps support my tinkering!).
