DIMM & SO-DIMM FIX + CLONE

It can hold up to 32 pieces of DIMM and up to 64 pieces of SO-DIMM modules.
If you store modules with heatsink then the capacity may be less than ½.
It's stackable design, but NOT compatible with the original.
Printed from low cost 0.22mm PETG with 25% infill. 
Print time in my K1 is about 2 hours and 20 minutes.

These module types will fit easily (tested): SDRAM, DDR, DDR2, DDR3 and DDR4 DIMM and SDRAM, DDR, DDR2 and DDR3 SO-DIMM.

Do not use PLA for this. It's really fragile and may broke just like my prototype printed from PLA. I'm recommending to print from PETG or other material with its properties.

I've fixed the size of this tray so SO-DIMM modules fits just the right way (96% of the original width). Then I cloned it and merged two models together. It's designed for those who have more than just few memory modules to store. You can store both sizes of RAM modules at the same time.
