for larger external cdrom drives. uses 1 28byj stepper motors. cdrom needs to be opened and closed twice to get the cdrom out and new one loaded.
how it works, drive opens pops the cd up then closes and slides the cd onto the top of the drive. pushes old cd off the top while pushing new one in, drive opens back up then pushes new cd into the drive and closes again.
glue a 1/4 inch nut on the end of the popper and attach a 1/4 inch bolt to the counter weight side. also you will need a servo hotglued to the front of the drive bay to enable the popper.
as of christmas 2018 the cheepest bulk dvd burner on ebay is 8-19 thousand dollars.
a rubber band wheeled version near the front might work better yet, i'll have to see when my all metal mk10 hotend throat gets here.

the angle on the tower was a bit too steep and tall maybe, but i found if you rest the back legs over the backside of the unit there is enough room to guide the cd's in and slow them down. i also added paper towel to the mouth of the dispenser with some hotglue.
also use hot water to reshape the slide if needed put a nice curve in it.
would be nice to be able to buy blueray's full of linux source code / virtual machines (might start working on that soon hopefully).
if you burn alot of dvd's you would want do this in a separate room or with good ventilation they do make a bit of stink after a full 8gb burn.
