The open-source syringe pump is designed for large syringes; this mod adds a small part for its Open syringe clamp modification to allow using smaller syringes by attaching this part on top of the main syringe pump.

The openSCAD file (attached) can be altered easily to change sizes; However, with smaller syringe sizes the original part's depth must be scaled so that the parts fit between plunger and tube.
