Having issues with microscopic slides shifting within my Foldscope 2.0 while panning, I needed something to keep the slides in place. I designed an adapter to fit snugly in the Foldscope. Here it is for you to download and print. The 3D model is also available in TinkerCAD.
I printed the model with 0.1 mm layer height using only PETG. PLA might also work, though it might be too bristle.
The author marked this model as their own original creation.
