Here are some 3D models for a custom breadboard just in case you need it for some project. It's here with and without the logo and feet that hold it onto a PCB. There are also 3D models for the spring contacts that can mount to a PCB, I'm having these custom made so If you hit me up I can get some to you.
Eventually they'll be up on my Tindie store
The Fusion 360 files are too big to upload so you can find them here at this Google Drive link
These clips fit a WS2812C-2020 addressable RGB LEDs in the middle. (older design shown here)
