If you own a Sebo Felix / Sebo Dart (or Karcher CV300/CV380 / Windsor Axcess in USA), you can remove the cleaning head and use the vacuum as a canister cleaner. Sebo sell a shoulder strap (part 7158) that connects onto the bottom of the cleaner body where the cleaning head would connect to, but...
So I have printed my own, based on measurements from the different heads that can attach to the cleaner body.
The other end of the strap attaches to the tool holder on the handle. I found strong cable ties work well to attach the strap to the handle end of the cleaner. The printed adaptor has a slot for threading a strap through but a strong cable tie can be used instead, depending on the strap you can find.
Printed in black PLA, 40% Infill, no support needed.
Print catch dowel pin with brim if it falls over during printing.
A short 10mm spring works well for the catch mechanism.
