About the hose adapter generator
Connecting a shop vac to a saw, a hose to a fan, or one tube diameter to another always runs into a size mismatch. This adapter joins any two diameters with a 45° transition that prints without supports.
For each end, you choose whether the number is the outside diameter (the end goes into the other tube) or the inside diameter (the end slips over the tube). The generator works out the wall and puts the wider end at the bottom.
What you can adjust
Inside or over
Each end can fit inside or over.
45° transition
Prints without supports.
Length and wall
Ends 5 to 100 mm long, wall 1.2 to 5 mm.
Ideas for use

FAQ
What does "outside" and "inside" diameter mean?
Outside: the adapter end goes into the tube, so enter the tube's inside diameter. Inside: the adapter slips over the tube, so enter the tube's outside diameter.
Is it watertight?
At low pressure, yes, with 3 perimeters. For pressurized hoses, add a hose clamp.
Is it free?
Yes. The maker and the editor are free and run in your browser. Without an account, the project is kept for 48 hours; with a free account, it is kept in your account.
Which format do I download?
3MF (recommended: keeps colors and opens directly in Bambu Studio, OrcaSlicer and Creality Print), STL or OBJ, always in millimeters.
