Home improvement: Pegovo cordless vacuum wall mount / accessory holder

After much comparison shopping, I bought a PEGOVO wet/dry cordless hand vacuum cleaner. When it arrived, I hadn't realized that it didn't come with a wall mount!

So I designed this one. It holds not just the vacuum unit, but also all of the accessories and has a channel for the power cord in the back.

This model is designed specifically for the Pegovo cordless vacuum. It is unlikely to work for anything else unless the handle configuration is the same.

The one minor annoyance remaining is that the shape of the vacuum unit body partially hides the charging connector from view, resulting in attempts to remove the unit from the mount without disconnecting the charger first.

Print Settings

Printer: Prusa I3 MK3S

Supports: Yes

Resolution: 0.20-0.30mm layers, 0.4mm nozzle

Infill: 15% cubic

Filament: Prusament transparent PETG

Notes

Print with any material that has good layer adhesion. Silk-texture PLA has poor layer adhesion and may eventually fatigue, causing the hook to break off. I printed this with transparent PETG at 0.30 mm layer height. Support is required for one accessory holder that sticks out. Support should be from build plate only.

Post-printing

1. Find a stud in your wall to screw into.
2. One screw hole is not accessible to the screwdriver after installation. Mark the screw locations on the wall first (they are 81 mm apart).
3. Install the screws so that the wall mount can slide onto them.
4. Adjust the screws as needed for a snug fit.
5. Once it slides on snugly, gently tighten the top screw.
6. If your wall isn't flat, you may need to insert some card-stock shims behind the wall mount to keep it from wiggling.

How I designed this

I spent way more time on this than intended. I originally wanted to make a kind of cup that the pointy end of the unit slides into, but I eventually settled on a hook. Either way, this project would have been easier if I had a 3D model of the cordless vacuum to design around. It's a complex shape with many curves.

My photogrammetry attempt at making a 3D model of the Pegovo unit resulted in a good model of the table and surroundings, but not the target object, because I didn't realize that photogrammetry doesn't work at all when the object has shiny or transparent surfaces. Photogrammetry works best with matte or rough surfaces.

So I ended up just making careful measurements as best as I could, and designing the hook accordingly in OpenSCAD. I didn't want to print this more than once. I wanted to get it right the first time. This was a case of "measure twice, cut once" but in my case I quintuple-checked every measurement, displaying the final mount on the screen at full scale and holding the vacuum unit in front of it to gauge the final fit.
