I bought a VESA mount arm from Ergotron. I wanted to be able to reposition my laptop for better ergonomics but I wanted to be able to still use it as a tablet (possibly while standing). There are several VESA mount options for laptops, but none seemed to suit my needs. I decided to build this out of Plexiglas and several screws with nuts and washers. Here's what you'll need to build this
An X-series tablet (The measurements may vary, I have the X61t).
A drill with appropriate bit.
Some measuring utensils.
And some consumables:
1 sheet of Plexi that is 12" x 10 3/4" x 1/4"
2 sheets of Plexi that are 2" x 10 3/4"
4 5/32 1" metal screws
7 5/32 2" metal screws
22 5/32 washers
11 5/32 nuts
The Plexi and fasteners cost me about $20. I even had the Plexi cut (if you live in/near NYC go to Canal Plastics like I did. It's a great resource).
Step 1: Measure/drill Holes in the Large Piece of Plexi
You will need to put three holes at the top as well. On my laptop there is a GSM modem antenna which makes the top uneven. I chose to put the three top screws off to the side so that it would not interfere or put any load on the antenna. YMMV depending on your laptop.
I also used the laptop itself to determine the placement of the holes. This was easy and helped me to make sure that the laptop would fit in the final product.
Step 2: Measure/drill Holes in the Two Small Pieces of Plexi
Step 3: Mark and Drill the VESA Mount Holes in the Large Piece of Plexi
Step 4: Mount the Large Piece of Plexi to the VESA Arm
Step 5: Attach the Small Pieces of Plastic, Insert Laptop, Enjoy Better Posture
Read the manual for the VESA arm you have. You may need to adjust the arms tension depending on the weight and position of your laptop. You should also position your laptop so that you are comfortable and in a neutral position. It's good for you.
