3 perimeters and 1mm top and bottom solid thickness is optimal (or use my PrusaSlicer 3mf with special raised walls and raised infill for the rod part of the model)
additional parts:
3 screws
1 small tightening strap (2.5mm wide) to fix DC connector of charger inside bottom hole of the holder (see photos)
or hot gun glue to fix connector inside the hole
tested for VP4353 model of Concept handheld vacuum cleaner, but probably fits VP4354, VP4351, VP4350
