I made a simple holder that slides over the exterior of the A1 screen, and holds a 1.89" x 1.13" x 0.6" (48mm x 28mm x 15mm) sized Digital Temperature Humidity Meter

Slides right onto the A1 screen, no tools or adhesives required.
And small hydro/temp screen fits into rectangle pocket.
The slight angle of the screen allows you to see the screen while you are sitting 

Will be making a better looking print soon lol
