Solder Paste Syringe Holder
thingiverse
This is a Solder Paste syringe holder. I used PETG but any media will probably work. Note that most solder mfg's want you to store syringes vertically tip down - from AIM - https://aimsolder.com/sites/default/files/aim_paste_handling_guideline_revnf1.pdf : "Solder paste in cartridges or syringe packaging should be stored vertically, tip down when possible." The tubing is K&S 83031 1/4 x 0.035" which can be tapped for a 10-32 screw thread. I made mine 3.5" long. https://ksmetals.com/collections/aluminum/products/alt035-1-4 It fits in a $29 USD mini fridge like this - https://www.walmart.com/ip/Personal-Chiller-Mini-Fridge-Black-Marble-K4107MRBK/268299430 - can easily fit on a shelf or bench top.
