This is a stand for any tablet and bluetooth keyboard combination. Simply print one of each and a mirrored version of each and assemble with a bolt and screw. This is adjustable by using the variables at the top to change length, width, depth, and shell thickness of your print.
A typical cheap stand will cost you $20 dollars, but a specific stand to fit your keyboard and tablet would be more toward $40-$60 dollars. This costs 0.68 cents to print.
