After having a small kitchen remodel done, my wife and I went to put things back where they go. We found that we had lost a small plastic part that made these canvas basket shelves work right. Her first thought was to pick up a replacement part at Lowe's. We arrived in the section to find that they didn't sell this 2 cent plastic part by itself. Buying a new shelf for the cheap plastic part would have been $30/us. Our trip to Lowe's was based on looking at their smart home system Iris. I was distracted by new technology and was thinking about all the options. She was about to purchase it when I remembered the magic machine that she so kindly purchased me on my 30th birthday! A few minutes in TinkerCad and we have the part we need.
This was one of the promises with this technology; that I wouldn't get screwed by large companies gouging me for some cheap replacement plastic part. This part is so silly that they don't even bother selling it. It keeps tension on the rail slides and allows the basket to move in and out properly. Silly, but the damm shelf is garbage without it. Thankfully, I had the other part to model it after and everything is good now.
