One of the most questions for us makers and 3d printer users is:
"what to do with the empty spools?"
There are many solutions around here, mine I'll introduce now:
I started with just drilling different holes in the spools and sorted my screwdrivers, pliers and files in. This was a makeshift and not satisfying on long term use.
The actual version is out now and relies on the spool as the biggest part of material, that you can save by not printing.
Also tools are no longer roaming around on the desk, because its fun to make them turn in the carousel.
It's a challenge to fit all tools with less different versions of holder bits. Sure the tools size is limited and not to use for heavy tools like 3" plumber pliers ;)
Anyway feel free to develop new bits.
--UPDATE-- 19.2.2019: Added new bits: Holders for 6,3 mm and 4mm bits, also a closed one for pens.
The foot is made to screw it on a piece of wood or direct on your bench. Its highly recommend to screw it somewhere.
At least the design depends on the formfutura filament spool i use often, but i figured out that many clear spools had the almost same dimensions.
If you're familiar with fusion360, you can tune some parameters to make it better fit on your spools.

The bits and the spike need supports for printing. The bits should be turned upside down before.
The mech part
after printing and removing the supports you had to tap an 8mm thread in the middle hole of the foot.
There you can screw in the rod which is carrying the spike. The shortest form needs a washer between the foot and the spike. If you need to fit the spool higher just fit two M8 nuts above.
Cut the rod depending to your needs and final height of the spool.
