Syringe nozzle adapter (drill out hole)

cults3d

I printed this 3-set. The largest was the best fit. I needed them to inject from a syringe into a .125" (1/8") silicone tubing. Steps: 1. Print (I did .26mm layer height). I used ABS. 1b. The hole will likely be sealed up. 2. Use a tiny drill bit, like 1/16", to open up the hole. It took a bit with my manual pen drill. 3a. I used a paintbrush and brushed some acetone into and onto the parts, this was to fixate any tiny pieces of plastic, smooth the surfaces a bit, and seal the surfaces. 3b. I then test-fit onto a syringe, then put the syringe down into the acetone container -- JUST INTO THE VAPOR. When putting liquid acetone on things, a powdery/milky surface can form from the fast evaporation. Even the room temperature acetone vapor in a container is sufficient to dissolve it into a nice smooth surface. *Note: It is designed to fit within a syringe lluer lock, but it's NOT designed to actually thread to the lock.
