This is a generic cable holder/wall hook to store a power cable from an electronic device (like a dust buster) while the device is in use.
To attach to wall, use a removable adhesive strip like a 3m command mini strip.
This holder is sized for a 1.5" x 0.5" adhesive strip. You can of course scale it to any size that's useful for your application.
I added a version 2 model which squares off the bottom edge to ease removal by making the command strip removal tab easier to grab.
This took 40 minutes on my printer at medium (0.2mm) resolution with 20% infill.
