This part may be attached to a robot arm to pick up lids of petri dishes when connected to a vacuum pump.
The part has a GoPro compatible fitting to join to the robot arm.
By default, the design has three nozzles, but this is customisable.

The multi-nozzle was printed with the default parameter values using about 17 grams of PLA filament, at a layer height of 0.15 mm and infill of 15%. The heated bed temperature was 62 C for the first layer and 60 C afterward. The print time was 1 hour and 55 minutes. The part is printed with the nozzles at the top of the print.
Printed suction cups, made from a flexible material such as thermoplastic polyurethane (TPU), must be fitted onto each of the barbed nozzles.
Some prints were made using TPU, and I found that the design needs some modifications are needed, so this is still a work in progress.
