Blow hose swivel

thingiverse

Human: Glassblowing and lampworking swivel for air line. This can be scaled up or down for various hose diameters, and used for any application requiring a swivel adapter on an air line that doesn't necessarily need a sealed swivel. Initially printed in PLA plastic. Print two of each model (two hose barb ends, two half-cubes). 0.7% scale prints perfectly for a 1/4" latex hose. 1.0% scale prints perfectly for a 3/8" latex hose. Designed using 3D modeling software. Initially printed on a Prusa i3 printer with an upgraded hot end. If you need a swivel and have access to a printer, this should suffice until a brass swivel is available. A mouthpiece and mold for creating a silicone blowpipe adapter are in development. I won't discourage others from creating similar products. Protips: >It's essential to note that this swivel will not seal well, resulting in air pressure leaks. You'll need to blow or suck more forcefully than with a brass swivel for optimal performance. >I recommend applying superglue to the outer edges of the mating surfaces on the two cube halves. >The first prototype involved gluing one barb to the cube and sealing it with superglue. While this showed some marginal improvement, it's not recommended as it didn't significantly enhance performance. >It's a good idea to install one of the hose barbs into your blowhose before assembling the swivel for better results.
