Privacy Window E-Shade. Suspension tight or Let it Sag, go for it!! I mainly did this for daytime privacy and indoor photosynthesis but perhaps with more patience Id think a pixelated image could be calculated and made into something outstanding!
Available in single and triple wide mount versions. I had figured leaving room to add depth or the shade density wasn't satisfying. Just a simple set of meshes that allow me to connect printed links of chain across window. PRINT MOUNTS and STRINGER in ABS or PETG (PLA will sag, trust me the weight adds. Pictured >1.0Kg). The Vertical runs support their own length easily. Chain Links join by cross section. I recommend playing with the Scale of the links, larger links create bigger light holes and the scale range of which links are compatible is wide. Is it expressive, economical, practical, or a lesson of patience....YES!!!
I wanted a way to use alot of my spools of filament that dont quite have enough left for any other purposeful printing/large projects. Single link can be scaled to your preference. I usually print them by the plate at 40-50% scale, 35-55pcs will fit the K1C(220mmx220mm). Usually each plate means roughly 4-6ft lengths at 15m of filament ea. Do you really need another Benchy?!

Future idea. Id Like to eventually make a close spaced set of "half hooks" that run along a vertical railpanel in a doorway for the "beaded doorway" aesthetic next.
Future idea2. A small stepper Scottish Yoke Mount to watch waves/ resonance kinetic art.
