This is a holder for a mini wireless keyboard. I've seen the keyboard branded or Amazon with a few different names such as Ambolove or Anewish. Here's a link to the keyboard https://www.amazon.com/dp/B077HZ7YJ2/ref=sspa_dk_detail_2?psc=1&pd_rd_i=B077HZ7YJ2 . I used some high strength 1" double sided tape to affix it. https://www.homedepot.com/p/3M-Scotch-1-in-x-1-33-yds-Permanent-Double-Sided-Extreme-Mounting-Tape-414-48/205532219

I printed it on it's side with supports inside. I used a .4mm for one and a .8mm nozzle for another. Both turned out great.
