Let me guess. You have a closet full of 3D printers. It's got a clothes hanger bar, but you don't have clothes, because who needs to go outside when you have a closet 3D printers?
Put that storage space to use with this hanger! See it in action in this video: [put video here]
You'll need at least two hangers, ideally one each foot or so. For each, print:
1x Hanger Hook
1x Hanger Hub
2x Long Bar
1x Short Bar
1x Hanger Corner
1x Hanger Corner (mirrored)
You'll also want a pile of Wheels, ideally in multiples of four.
You'll also need:
8mm metal rod, long as you want, cheapest you can find
4x 12mm M3 screws and M3 nuts per hanger
A pile of 608 bearings, ideally in multiples of 4
Instructions!
Glue everything but the hook and wheels together
Mount the Hook on one side with an M3 screw and nut
Insert an M3 screw into one or two pockets on each side, add the screws, don't tighten too far
