A simple chunky tablet stand with two angles of viewing for you tablet, two versions, the "slimmer" version just reduces the thickness of the support beam between the two angled surfaces. The idea of the four separate feet is to allow the stand to be easily used on uneven surfaces such as the arm of a sofa.
Designed to take suction cups in the feet although perfectly functional without. I've used some generic 40mm suction cups I sourced on Amazon. These are the ones I bought: https://www.amazon.co.uk/dp/B008B7XCVS/ref=cm_sw_r_oth_tai_jiX5ybJEE9W8V
Will print without support, I've printed in both PLA and ABS without issue. One note on printing in PLA is that I find it a lot more noisy putting the tablet on and off and moving it around on hard surfaces.
