Matthew Meyer 3D-Printed Design
From Matthew: The 3D printed version of the main body is very sturdy and shows little risk of bending or breaking under any normal strain. 3DPumpy is a constant work in progress but I am excited to announce enough improvements from the original design to call this next iteration v2.5. Version 2.5 uses less filament to print, provides greater stability for the linear actuators, and has a v-slot as a universal way to insert the base of syringe plungers. The slots you place the linear-actuator in is now precisely molded to the Lego part and therefore much more snug, providing vertical stabilization. Additionally, I've added an extra appendage that attaches to the bars above the linear-actuator, providing horizontal stabilization. There are four different flavors of Pumpy now, Solid, Drippy, Skeleton, and Pumpy. The first three are variations on the original Lego-Pumpy design but Puppy-Pumpy is a completely different layout which is designed to be compact and for high-speed dispensing purposes. I have also created adapters for 60, 10, 5, and 3mL BD syringes that attach to the end of the linear actuators and hold onto the arms of the syringe. These adapters, alongside the v-slot, completely eliminate the need for rubber-bands and are very sturdy.
Note: Matthew keeps a google drive folder with updated versions of his designs here.
