Holders for Wago 221 Gridfinity prototyping board

How to print:
- 10 to 15% gyroid infill works well enough with a modern printer
- 2 walls
- Make sure the seam is out of the opening, paint it on the outside if the fit is too snug it might help. 
You can probably get away with less but this is already a light and quick print as is. 

The connector should be pushed with some force into the holder and should be firmly seated in it. 

Start by only printing a 1U connector to test if the print works for you. 

Issues you might encounter might be inappropriate tolerances, if you do please report back and I can upload additional models with updated tolerances if this is a common enough problem but this should work for most people. The STEP files are available.

- Gridfinitylicious, it is compatible with all grids in the gridfinity ecosystem. I find the synergy with @NoWarrenty's  clickfinity particularly good. 

- No magnet holes, nothing against them, just don't like 'em. 

- Usable with mains/utility voltage, wago connectors will handle a lot more current than your typical board. Please still use common sense, in how you use this. 

- Center hole that will fit your standard 3,5 screw to securely mount it, can also be used to easily remove the wago from the holder. The test feature of the wago connector is also still accessible through this hole

- Relatively light on the filament required, a 1U holder will need around 8g of plastic depending on your settings. This is great to finish your spools 

- Colors! Use your silks, your fluorescents, your pastels, your shinies, and your matte black filament if you are boring like me; the world is your oyster. That damn data pin 16 is now easy to find in that shiny pink filament you finally get to use.

- Pogo pins don't fall out of your board, because you are not using them, probably the best thing about this ecosystem is how secure wires are without being permanent. 

- Solderless-ish, you should probably still solder wires to the components you use because you are not an absolute barbarian who sticks the legs of a diode in two wagos and calls it a day. If you do this please seek help. 

- Modularity and other buzzwords, it does that too, really cool, thanks Oli. 

What this is not:

- Safe, you are working on potentially lethal levels of voltage. Odds are if you are reading this you do not need to be warned but please be aware that if you do not know how mains voltage can kill you, you should not be working with them. Because they will kill you and it will hurt the entire time. 

- Cheap, your standard breadboard is approximately ten times cheaper than this, but it's neither orange nor does it click. But if you are anything like me you buy wago connectors in bulk and always have a bunch of them lying around, plus you can easily scavenge them back. 

- Rated for the small wire gauges used in typical hobbyist electronic circuits, wago connectors will usually hold them but they are not rated for really thin wires and you should not be mad at them if they don't. 

- Hexagons, their absence is extremely sad, I am working on it. 



If people are interested I might add some other features like different number of U holders instead of the standard 1 or 5U,  or dedicated power bus bars or esp32 pinout with pre-existing embossing, etc
I didn't really see the point of 412 version but I'm open to making it if is needed.
 
I am open to all suggestions and will greatly enjoy pictures of your projects. :)  



PS: don't pay attention to the exemple circuit, this is nonsensical and only used the showcase some of the possibilites of the ecosystem.
