Nintendo Switch Cartridge holder x8

After showing a friend on campus my previous design, I decided to scale it up. I wanted a cartridge holder for my games. which is why I created the single cartridge holder.  now this one is better, 8 times better actually.   With a simple push button release, this holder is truely a joy to use. I wanted something that wouldn't just drop these expensive little guys when ever it wanted. I went through a couple revisions and this one worked the best. I was banging on this this for a couple minutes and it wouldnt come out. Heres a gif of me banging it against my windowsill  http://imgur.com/a/TYvMl   .2mm layers of pla 1.05mm wall thickness 1.5mm top and bottom thickness
