Cisco 9841/9851/9861/9871 Phone Wall Mount

My workplace upgraded phones to the Cisco 9800 series and couldn't justify paying $70+ for a phone mount, so I designed this one.  This mount is a two-piece design:  one part mounts on the phone, the other part mounts on the wall, and the two screw together.  If you're looking for a simpler mount, or need to mount the phone to a phone wallplate, check out my other model:

It was designed to be printed in ABS, but most other filaments should also be fine.  It can be printed without supports if printed in the original orientation.  I printed these out with 3 walls, 4 top and bottom layers, and 20% infill.  Use a brim for the phone mount half unless you're confident in your printer's build plate adhesion.

There are three versions of the mount available, each using different fasteners to attach the halves together.

Here's the list of fasteners you'll need:

• Metric Heatset Inserts

  • 2 - M3 x 12mm or M3 x 16mm machine screws

  • 2 - M3 heatset inserts (M3 x 5mm OD x 4-6mm L)

    • Something like these:  https://www.amazon.com/dp/B0D7M3LJDL/

  • 2 - M3 hex nuts

  • 2 - #6 x 1/2" or #6 x 5/8" machine screws

Installation:

• Install the heatset inserts or hex nuts into the wall mount half.  For the heatset inserts, heat up a soldering iron to 150-200C and push the inserts into the part as straight as possible.  The hex nuts just slide into the front of the part.

• Attach the phone mount half to the back of the phone using the wood/sheet metal screws.

• Attach the wall mount to the wall using wall anchors.  Pick any 2 or 3 holes on the mount to use.  The side with the countersinks and hex nut slots face away from the wall.  (The top of the phone is roughly 75mm or 3" from the top of the wall mount half)

• Hook up the necessary cables on the back of the phone.

• Mount the phone on the wall and attach the two mount halves together using the machine screws.
