Seeing if there is any market for this product and custom parts. I will be printing them at home.
First the mount :



I use it for data entry on my Supervisor tablet. The Anker keyboard will bind with any device that has bluetooth (windows/android/mac) but it's up to you to determine compatibility. It's durable, light weight and adjustable. The white parts are 3d printed in ABS and the arm is aluminum.
You can buy the keyboard here :

For the mount I'm asking $60 shipped.
I would also like to try out making custom parts for surveyors. If you need to mount another type of hardware on a pole, or need something designed and printed I can most likely come up with something that works. If you have something that is broken I could probably replicate the part. I can provide you a quote once I get an idea on the size of the product.
Can you scan a part to create a 3d model to print? The piece being about 1" x 1.5" x 3"?
My email is good.
Sent you a message.
