8 channel vacuum aspirator

LABWARE: This is an 8 channel adapter to be attached to a vacuum pump - a very useful tool if you need to remove solutions from 8 wells simultaneously on a 96 well plate.
I designed this trying to keep it a simple print and easy assemble. If you are familiar whit this labware, you will notice there is no spring: I believe this way it's easier to be put together. You just need to add a screww as indicated.
You can print it using the file with all the pieces or the single files.
 At the moment, I am printing in PLA at 50% infill, tested for one year now, perfect.

If you know the item, you also know how cheap is to print it as compared to the Commercial ones, which  are around 300 euros.
