UPDATED 5/2/2019 - I have included more tray types and changed the names of the trays so hopefully they will be easier to understand. The trays are divided by height 16 mm or 24 mm. The 16mm size is 1/3 size and the 24mm are 1/2 size. The 'pockets' indicated the number of separate compartments in each tray. "SS" indicates the tray has sloping sides - for easy one-finger removal of small parts. I have also slightly changed the sloping sides so they work better.
If you have a different tray system than eSun these will still work. eSun is slightly larger than most spools so the trays will fit but be loose. If you want an exact fit I suggest using the scaling option in your slicer. Print the 16mm size and then determine how much you want to change the size.
Also, I suggest you print these at 0.35 layer heigth (for Prusa MK2.5) or 0.3 layer heigth (for Prusa MK 0.3). The quality will be very good and the print time greatly reduced.
UPDATED 2/17/2019 - to include trays with a sloping slides
This is not a true remix but and enhancement of a great thing by ElmoC #2141153. I needed more storage for small parts, and I needed easy access. Small parts in a large bin is not easy to use! The trays are categorized as 1/2 height or 1/3 height, 0,1,or 2 dividers each, and sloping sides (SS). No 'SS' in name indicates there are straight sides.
I have updated the files 2/17/2019. The sloping side allows you to use one finger to reach in and grab a single or multiple items and slide them out without a tool.
The drawers with no dividers have a center pole to grab for easy lifting. I found the 'no divider' drawer very good for Allen wrenches and small wires (I have my spare bed thermistors stored in this tray).
The trays are make with Fusion 360 and are optimized for printing at 0.2 layer height.
