Adapter for Airbeds with a Boston Valve.
The adapter screws onto the valve (instead of the cap). The pump-side of the adapter is designed to fit a Vaude Pumpsack - but with the provided OpenSCAD file customizations to fit almost any air source are possible.
The threads were created with the OpenScad threads.scad module released with CC0 into the public domain by Ryan Colyer.
Print with a layer height of 0.15 mm (only tested using PETG, but PLA should work just fine).
The author marked this model as their own original creation.
