Kärcher WD3 - Vacuum Cleaner Bypass "Valve"

thingiverse

To make lifting the vacuum cleaner easier when it gets stuck on the carpet like concrete, simply slide open the valve. This method is quick and effective, although it lacks a locking mechanism and may require some sanding to get the job done properly. It's designed to fit onto the WD3 tube handle. Before attempting this fix, you'll need to create a sufficiently large hole in the vacuum cleaner.
