PU foam is a building material used for fixing windows, sealing air gaps in houses, waterproofing, etc. It is shipped in pressurized canisters that need a special extraction pistol to apply it to the desired surface. This pistols are usually pretty common, but parts for them aren't, so i designed this pistol in solidworks to have all parts on hand if something brakes. The photos show the final assembly made from 11 parts that all have different uses and are all designed from a real PU gun. I've also made the full technical documentation including shop drawings and a composite drawing. The project took around a week and it also features all of the functionalities of a real PU gun in solidworks.
