Various brackets to stack 2 (or more) 1541 floppy drives on top of each other.

The weight of the bottom device keeps everything stable.

The space in between provides enough room for ventilation.

I designed 4 models:

Single: a separate stand that can be placed anywhere (4 required)
Double: For the sides. The legs fit between the rubber feet of the 1541 (2 required)
Middle: Separate stand to connect and place multiple drives next to each other
Front / back: Bracket that slides over the front / back (2 required)

A combination of different stands is possible.

The brackets have been tested with:
Commodore 1541 drives, 1541-II drives and Oceanic OC-118N drives

I own more than 15 drives and was looking for a way to neatly stack them.
This is a hobby project, if desired I can upload the stepfiles

For the most stable setup I use 2x the side double brackets
