Wall mount for Lenovo Idea Tab 11" (Home Assistant)

A wall holder for the Lenovo Idea Tab 11, made to hang the tablet on the wall, in portrait or in landscape (separate model for each), as an always-on dashboard (for example Home Assistant in kiosk mode). The USB-C cable runs through the wall behind the holder, so no cable is visible.

Features

• Tablet slides in from the top and rests in a pocket with a soft, rounded front edge

• Open at the top, so you can lift the tablet out without tools

• Cable channel at the bottom for a right-angle (90 degree) USB-C plug

• Slot in the back plate with a groove that leads the cable to a large opening, so it fits over a wall box or a recessed cable outlet

• 2 keyhole slots at the top and 2 screw holes at the bottom, with recessed screw heads

• Prints in one piece, back side flat on the bed, no supports

• Two models: portrait and landscape, each with keyholes placed so the holder hangs by gravity

Dimensions

• Holder: 171 x 193.7 x 14 mm (portrait), 193.7 x 171 x 14 mm (landscape)

• Tablet pocket: about 255.4 x 167 x 7.4 mm (0.4 mm clearance per side)

• Tablet it was designed for: Lenovo Idea Tab 11, 254.6 x 166.2 x 7.0 mm

• About two thirds of the tablet is held, the top part sticks out

Check before you print: measure your tablet. Other 11 inch tablets with the same outer size should fit, but the USB-C port position and plug clearance differ per model.

Hardware you need

• 4 wall screws with matching plugs. Top (keyholes): head up to 9.5 mm, shaft up to 4.6 mm. Bottom: shaft up to 4.6 mm, head up to 10 mm (recess 3 mm deep).

• A right-angle USB-C plug, body up to about 8.5 mm thick

Mounting

1. Mark the 4 drill points on the wall: the two top screws 90 mm apart, the two bottom screws 136 mm apart (68 mm left and right of the center line). The bottom screws sit 145.7 mm lower than the top ones (133.7 mm hole distance in the model plus the 12 mm the holder slides down).

2. Use a level so the holder hangs straight.

3. Drill, insert plugs and screw in the two top screws, leaving about 4 mm of the shaft free.

4. Hang the holder on the top screws and slide it down 12 mm.

5. Fix the two bottom screws.

6. Route the cable through the back, connect the right-angle plug and lower the tablet into the holder.
