Note: 1x slot in this design refers to 1x level of screw holes, 3.5" HDD takes up 2 slots per drive

Also check the 2.5" variant: [https://makerworld.com/en/models/1921011-2-5-drive-cage-with-stackable-assembly#profileId-2061277](https://makerworld.com/en/models/1921011-2-5-drive-cage-with-stackable-assembly#profileId-2061277)

Update: Please use the updated print profile for a more fitting connector piece (which is now 105% scaled). Thank you! 

A hard drive cage design where you can assemble the cage with a custom number of slots, as well as stacking multiple of them. The slot panels also have holes for 2.5" drives (variant available but possible using longer M3 screws)

You can add more slots into the cage by printing more slot pieces and connect them with the modular connector pieces.

Note for the image: the version in the image does not have top and bottom shells, the modular connector pieces has been hot welded for integrity (not the most beautiful one ever but it sure holds up!).

Drives can be mounted with any M3 screws, personal measurements has made the holes to generate threads upon screw installation.
