This tool is a squeezer i use to force a viscous fluid through a syringe filter.

In the off chance that like me, you need to filter a syrup like fluid through a syringe filter, you will find it much easier to do with this than by hand...

Load the syringe and add some air to serve as a spring, put the syringe in the system and add the filter. Screw on the device and you can just patiently wait for the liquid to filter through.

Compatible with most 1 to 3 ml syringes. Only use syringe with a screw retention system if you don't want the filter to pop off inadvertently...

This design uses 1 M3 screw (10 to 20mm) to fix the head to the screw. I added the STEP file i case you want to modify the design.

Edit: I modified the "main body" part a little to be able to load the syringe with the filter attached. The corresponding file is "main body V2"
