20 Discs Scrolling Y2K Desktop CD/DVD Media Library

I got inspired by old home CD/DVD libraries from the giant Jukebox's machines from bars and diners and the 2000s Discs racks aesthetics of transparent plastics and Blobjects forms to create my own rack that can hold a substantial number of media's. But I wanted it to mechanically do something like have it scroll through the discs showing one disk at a time, so after some time thinking of a simple mechanism to achieve this, I came up with this design. It Basically a series of 3 arms that are divided into 3 separate tracks, forming a triangular helix that are guided linearly by the long-slotted shaft, so when you rotate the crank, it makes the arms follow the tracks and then pushes the disk trays upwards, then gravity forces them to go back down when continuing to turn. So originally, I made a single arm 20 rack version, but that made scrolling very slow by only showing a single disk at a time, so it would've taken 20 turns to show 20 disks, but lucky I thought about increasing the number of arms for this latest 3 arm version which now scrolls through all 20 disks in just 6.5 turns! Many times, faster than before! This is a Very large print that'll take 14+ hours and will used almost half of a full spool of filament, so make sure to enable outside brim only and apply glue to secure it to the build plate just in case. DISCLAIMER! I am not responsible for any damages to your printers or to the CD/DVD media that this model could do, I consider this a WORK IN PROGRESS, so its not officially finalized yet, just posting the latest one for progress and getting it out there!

Frame printed FACE DOWN with slots touching build plate, the actual base (The mechanism arch) on top! Designed this way to avoid supports, so its essentially upside down! Default settings for the frame.
Handle shaft is printed on the flat 45-degree angle, shaft point up with handle on build plate!
The 3 arms printed on the flat side with the cone part pointy end UP! with/without Brim optional (One file print 3 of those)
C clip with a brim

Trays are printed Separately (20 of them) using 0.08mm layer height, the rest should be default settings. I managed to print 4 trays at a time that takes 1 hour, but consistency vary in batch like prints.

Assembly is a little tricky, I designed the crank to be long, so it'll have stepped sized installation which makes you install one arm at a time. It'll be like, 1st arm in the flushed slot first, the 2nd arm in the halfway slot, then the 3rd arm in the longest slot last, this is a work in progress, so its not super intuitive/easy to install, but once you tried it with some disks it should crank to the last disk goes UP then DOWN crank end stops, and the last one on the other side goes up and then Down as well, so vis vera

Printer - Bambu Labs X1C
filament- Transparent PLA (It feels smoother and looks cooler) Other kinds of filament Not tested
supports- NO, but recommend adding BRIM OUTSIDE ONLY
