The easy stage ecosystem are a set of positioning stages that are fully 3D printed and only need basic M3 bolts to be assembled, though some silicone grease is recommended. They're gridfinity compatible and make building at home optical research setups much cheaper and easier. I actually made these to position an open sourced electrospray ion source I've built that I might post here when its more complete. I presented these along side the ion source at a British Mass Spectrometry Society (BMSS) conference earlier this year (the AI SIG 2025) where it won an award.

I'm planning on adding motorized versions of these in the near future, alongside a Z stage based around a scissor lift. I might also make some T8 threaded rod versions for moving heavier payloads. You can find the designs on my printables and on the github repo I made for this project linked below. All CAD is provided and was done in FreeCAD.
