This is a short two piece desktop book/recipe book and or tablet stand I use for display cue tablets I printed to write in sweeps coins entries. you can adjust size as needed, but it is stout for what I use it for. 

I used Inland translucent orange PETG for the top half at 60% infill with supports on my Bambulab A1.

I used Inland translucent blue PETG for the bottom half at 60% infill with no supports on my Bambulab A1.

The sizing and infill works for my application, you may want to adjust for yours. If you change the scale on the upper half, be sure to use the same scale for the lower half or you will run the risk of fitment issues.
