Compressed Air Vaccum Gripper (Prototype)

Hi,this is a prototype of a vacuum robot gripper that creates its own vaccum using the venturi effect. It weighs around 6 g and can lift things up to 1.5 g (I just blew into the air intake) EDIT: @DickF tested it and was able to lift 11.4 g at 6 bar. It also has a bracket so that you can mount it on your robot arm.It is still in an early stage and might change a lot in future versions. Its dimensions are approx:50 x 40 x 20 mmAir intake diameter: 5.5 mmConnections on bracket: 2 x Ø 5.5 mm; 30 mm apart How do you print it?It consists of only one part and can be printed in around 2 hours with supports. I recommend a 0.12 mm layer height, a 20% gyroid infill, inner walls width of 1 mm, tree supports and PLA. How do you use it?The gripper has 3 openings: Air intake (marked with “IN”)Air outlet (marked with “OUT”)Vaccum opening (not marked - please let me know if you know a better word for it)If you blow air into the air intake it will leave the gripper at the air outlet. This creates a vac
