Description: These are a set of four replacement feet for the Corona 3 typewriter from about 100 years ago. These amazing little machines typically still work great today, except the original rubber feet are long reduced to mush. I designed these to be nearly an identical replacement, but with the advantages of modern 3D printing technology we can engineer materials that were previously impossible. I printed with NinjaFlex black TPU polymer (https://ninjatek.com/ninjaflex/), which is nearly indestructible (but a knife or scissors will cut it, just like rubber!), flexible, and pretty gripping on most surfaces. Note, this auction is just for Typewriter Feet, and is related to my other auctions below:Full Kit: https://www.ebay.com/itm/174799840230Spool Nuts (Amazing Working Rubber Design): https://www.ebay.com/itm/174715233337Case Inside Feet/Rubber/Pads: https://www.ebay.com/itm/175808971517 Basically, EVERY piece of rubber on these ~100 year old machines needs to be replaced, so I suggest you don't buy just these parts, but instead purchase the above kit which includes everything at a better price. But, people have asked, so I have the individual parts listed as well. The special feature is these are printed with a solid bottom, but after a few layers for adhesion strength the top uses a 20% gyroid fill pattern (see the picture). The top is not load bearing, but merely slides into the socket to hold it in place, then the machine rests on the solid bottom part. The top is still super strong, but is more easily compressed to install into the typewriter, the originals are kind of hard to install. Some people may prefer the original dull rubber look (and I know those are also being made and sold), but I actually think these are a superior look to rubber, and the glossy finish better matches the rest of the machine. I also think these will last far longer than natural rubber without compressing or falling apart. Please ignore other's marketing claims that 3D printed feet have no grip, or that their feet are more "professional". Look at my reviews, these are beautiful and amazing typewriter feet being bought by collectors and dealers alike, I'm regularly told my feet are the best. I designed these for my own typewriter as shown, and this is an experiment to see if it's worth my time to make some more for the community. If you have access to a 3D printer, I have shared this design online here, feel free to print your own (just know that printing in 85A TPU is difficult): https://www.thingiverse.com/thing:4808479 PS: Ebay's volume discount display is a bit confusing, each purchase is a SET OF FOUR feet, so picking "1" is one set of 4; "2" is 2 sets of 4 (8), etc.
