Stabilizing a 3u spacebar

I am designing a layout with 3u spacebar and I would like to know my options on stabilizing it.

As far as I can see a 3u cherry stabilizer does not exist and needs to be made. I am wondering about using dummy switches since the stabilizer holes are exactly 1u apart. Does anybody have any experience or suggestions?

Thanks in advance.

Use a 2u stabilizer. Works well for 2.75u keys. 3u should still be okay

Getting caps will be fun though

The SA round group buys had 3u and 4u keycaps, that's probably the only choice. But I'm not sure which kind of stabs they use, I would expect 2u stabs for the 3u cap as this would work but you would have to look at all different manufacturers

I wrote the wrong measure. The stabs distance in my caps is 2u,not 1u. They are 1u apart from the center stem.

They exist! https://eu.mouser.com/Search/m_ProductD ... 7RTbZMU%3d . Let me know if you would like to buy some as I would love a few myself!

The option with dummy switches (i.e. switches without a spring) is a good idea (and, by the way, the standard solution used by Tipro in their keyboards). My Enter key works flawlessly with that.

3u space bars, exactly fitting 3 switches, but nevertheless using a stabilizer, can be found in Acces-IS point of sale keyboards

Mh, that is interesting, but I cannot understand if they are pcb mount or plate mount. Will try to contact them and make sure it is what I need. (I need plate)

According to

https://geekhack.org/index.php?topic=85933.0

They are pcb mount, but the part number for the plate mounted is provided in the above link
