I like to use 2u keys for my spacebars, but none exist in KLP Lamé (unless you want to pay for the 3dkeycaps extended version)t so I quickly knocked this 2u together in TinkerCAD. I haven't yet been able to print one for myself, but they're on the printer and I will share soon!

Probably best you print these in SLA Resin. It might work in FDM but I haven't tried!
