Until now I added adaptors for different hose-types to the Tenok 3D-file collection on thingiverse now and then. However, I decided to use yesterday evening to create a library of 22 adaptors for both single- and double-spiral hoses. Now you can use any common vacuum cleaner hose between Ø29mm and Ø50mm! I assume that range should work for 99% of all hoses, but if need be I can design smaller (and slightly bigger) adaptors in the future, too. If you happen to have a hose that doesn’t fit, let me know and we’ll figure something out.
