""not in America, which makes me suspect it's because of our lawyers" Or it's because of it's construction that makes it less than feasible for matching up to building codes. For example, the pop rivets at 0:24 in the installation video don't inspire confidence in its construction. That is a solvable issue though. I think the design is sound."
"I've got a bookcase/shelving made out of flat boards and industrial crates, and rather than use gravity to hold it together I used a tie-down ratchet strap. These techniques look like a much more elegant purpose made solution though."
"Literally an idea guy who's never made anything, selling an idea with no physical product and no proof of sale for this "auction"? Sounds like a crypto guy alright."
"I've got a microATX-format desktop and a drawing monitor I bought because the system itself was far higher performance than any comparably priced laptop, and with the drawing monitor I have no need for an attached screen. It's theoretically portable if it weren't for the 5-4 meters of cables between the system, monitor, as well as brick power supplies for both. Having to unplug, store, take out, plug, and repeat the spaghetti pile twice for every trip makes it less portable than I'd hoped. It'd be great if I could just place the whole setup into a box without unplugging everything. Unfortunately, with the concept of LAN parties being a thing of the pass there doesn't seem to be any container that could help with this."
"This is a neat idea. The main problem of non-pneumatic tires, variable weight, isn't an issue in this case. I think the real issue will be the same as all 3D printed products: incredibly slow manufacture time."
"Center-pull extraction is fairly common system of towel holder but typically institutional. It makes for a super simple towel dispenser with no moving parts, the only issue being the fact it requires a slightly non-standard paper towel roll. Not likely to be in stock at your usual grocery store, but almost any commercial supply company would have it. When you think about it, it's better for the environment given the lack of hard cardboard tube in the middle and the simplicity of manufacturing dispensing units."
