Syringe Guide - Parametric - Bottom Up

This aids in drawing up solution from a vial using a hypodermic needle. (Vial oriented “bottom up”, i.e. upside down.) See the attached image for the used dimensions. Adjust the parameters to your syringe and vial. Key points:Prints in place. Hinges will work without assembly.Windows allow view of vial and syringe.Orientation: This design is intended for drawing solution while the vial is “bottom up”, i.e. upside down. I have another design that allows drawing while the vial is oriented “top up”. Which version you should pick depends on the length of your hypodermic needle. Update 1: Now includes an additional parameter for easy draw syringes (and similar syringes) where a portion of the barrel extends beyond the flange. Update 2: Fixed an issue, where small vial diameters broke the model.
