Finally w have manged to mount our 3D printed labeno set on the lab wall. The advantages are many, as the lab equipment can be permanently installed, taking very little space eliminating setting up time. Students can now focus on their experiments with what we call a 3D printed stater kit made of a phone holder unit and a 3D printed pivot. Previously, we held them in lab stands, we still can. But lab stands can be a little shaky. The wall is much better.
