Shark WandVac Vertical charger conversion

This model is a replacement for the included desktop charging stand. It was designed to be wall mounted and use the original power supply. It has several parts and requires some specialized fasteners which can be found at most ACE hardware stores.

You can either permanently modify the power supply that came with your wand vac for this charger or buy an equivalent one. I've modified my originals since I have no interest in ever using the desktop stand charger. 

Printing

Print the blue parts (especially the “Clip” and contact “Spring”) in PETG, they need to have springiness to work correctly. You can try PLA but I recommend PETG, I prototyped in PLA and I think PETG works better. I print the green parts in PLA. PETG would probably work for those also but PLA is stronger, more rigid and cheaper so I use that.

No support is needed if you print in the orientation used in the 3mf. I used extra perimeters (4 I think) and concentric pattern for the bottom layer.

Required Hardware

    2 M3x12mm machine screws (any head, socket head suggested)

    2 M3x12mm machine screws button head or round head† for contacts

    2 M3x8mm machine screws (any head, socket head suggested)

    1 M3x6mm machine screw (any head, socket head suggested) [optional]

    5-9 mounting screws, drywall/grabber, wood screws or sheet metal screws #6 or #8 (M3.5 or M4) 

† Common socket head screws might work but for these electrical contacts a rounded side profile works better. If you can't locate rounded heads you might try sanding a socket head more round so the contact with the vac is better centered on the screw.   

Assembly Diagrams

Instructions

• Use the round or button head screws to attach the power supply wires to the contact spring. The washers are optional, just make sure the wire makes good electrical contact with the screw. I've had good success making a loop in the wire around a 4mm screw and tinning the wire with a solder pen. It helped to crimp it flat with pliers if the nut won't fit on the screw. The red wire goes on the side with the “+” symbol in the upper mount, see diagram and/or photo showing the back of the upper mount below.
   

• Use the M3x12 to attach the wedge and spring to the upper body. The wedge should have the end UP. It's purpose is the make the contacts stick out farther.
• Choose a cutout for the wire, there are two on the bottom and two above the top of the contact spring. Open the cutout with a knife so that the wire can fit.
   

• Screw on the “Keeper” with the M3x6 screw to keep the wire in position.
• Attach the “Clip” with the M3x10 screw in the outer holes. There's a third hole but this isn't needed and the screw heads are pretty close.
• Mount on the wall or a board <INSTRUCTIONS INCOMPLETE>
  • The charging stand (holder) needs a minimum of space 18" tall by 4" wide, an inch or two more in each direction will be more comfortable. 8" wide if you want to position the accessory holders next to the wand vac.
  • Draw a vertical line in pencil where you want the stand centered.
  • Position the top…
