Some months ago I bought the eVacuum Kit Pro from eSUN. I love it, because it is much more easy to vacuumate my 3D filaments, but I think, the electronic USB pump has one problem: The switch on the upper side, and also the cable hinders me to push the pump down on the valve with the needed force from the top, without hitting the switch and turning the pump off. So I decided to create a ring with TPU, that can be pushed on, and now it is an easy task to push the pump down :-)
Maybe You have similar problems, it should be no problem to scale the PushHelper as needed. Because of the used TPU the inside diameter should be around 1mm less than the diameter of the pump. The original diameter is 31.2mm, this is perfect for the pump from eSUN that has a range of diameter from 32mm to 34mm at the bottom.
