Wheeled case space saver

thingiverse

I have a wheeled laptop case and needed a way to neatly store small equipment (battery packs, etc.). I noticed that there was wasted space between the handle storage pillars at the rear of the case, which would easily accommodate the equipment but no way to hold it in place. So, this device clips between the two pillars to provide a neat and simple way of storing small items in there. I imagine it could be scaled easily enough to fit different cases. There are two different devices: one that has a "shelf" to prevent items from dropping and another that doesn't. This gives some flexibility in height.
