I had come across this hanging bike storage video a while back and thought it was pretty clever. The strut channel hardware wasn't easy to come by in my area so I 3d printed the blocks to make it happen.

I would like to get longer strut but for now it works pretty good for getting the kids bikes off the floor until the next one grows into it.

Each hanging roller requires:

• two 5/16" diamter metal rods cut to 34.6mm long 
• four 608 bearings, I salvaged mine from broken scooters and skateboards over the years. 
• one 3/8-16" vinyl coated hook 

Each end cap requires:

• one 3/8-16 unc x 0.75 bolt 
• one 3/8-16 unc nut

Strut channel is 1 5/8" x 1 5/8" cut to whatever length you like. 

STL's are orientated as I feel best suited for printing.
