Sponge: Hot Plate Glue Dispenser

thingiverse

Insert a cut-out "Scotch Bright" sponge into a Ball Jar. Use 300 mL of glue solution to create an air gap between the sponge and the liquid. Close the jar and shake it vigorously to refresh the glue on the sponge. Customize your setup with OnShape, a powerful CAD software. Typically, use two jars: one for the glue solution and another for the wash solution. To prepare the glue solution, mix 50 ml of Elmer PVA Glue-All with 250 ml of water. For the wash solution, combine 50 ml of Isopropyl Alcohol 90% with 250 ml of water. Some helpful tips to keep in mind: if your lid gets stuck, submerge it in hot water at 140 F for one minute to loosen it.
