As everyone knows the original sleeve of EIKI projectors focus knobs gets gummy over time and loses its capacity to hold the lens in place. Here is an STL file of a replacement sleeve designed by Christophe Goulard, to be printed in 3D. You can print one, or 33 of them at the time, and make sure all your projectors stay sharp in a single shot!
To make sure it works well, we recommend printing it using TPU (Thermoplastic polyurethane). Then it’s firm enough to hold the lens and soft enough to give it way. Perfect!
