This is an extremely simple organizer design. I couldn't find any parametric organizer designs in here, so I decided that it is a great opportunity to take a bite of OpenSCAD.
I needed to tidy up my workspace working as a sysadmin, having tons of different disks replaced, reused, failed etc. and the space on the shelves in the "storage" facility got used up.
I designed this in order to have a parametric disk tray, for the needs of a few friends because not exactly everyone has 53 spare ssds and 120 2.5 disks laying around.
I have around 20 different disks at home scattered all over the place, so this design is a good start.
The combined .scad with the all slots is rather ugly calculated but it does the job.
Printing with Prusa i3 MK3.
Printing at 0.3 layer height also should be fine.
Step 0: Use Proper Filament
First I used a cheap filament for which I am truly sorry.
The Prusa PLA Silver turned out to be great, and I regret not ordering a couple more filament rolls together when I ordered the printer.
Step 1: Change Base dimensions
baselen = 230;
basedepth = 200;
baseheight = 70;
Change these dimensions to form the block tray which will hold the slots.
Step 2: Add necessary slots or columns/rows
Down below at the bottom of the .scad file there is a difference() section which contains calculates the blocks.
Add your disk columns/rows(which are rotated columns) to your preference with the position and the amount of slots.
If you want to add different types of slots on the same organizer, you will have to calculate by hand the different slots' offsets.
