This is a set of replacement feet for *I think all* Hermes Rocket and Baby typewriters. I believe these have now been tested on all variants of these machines. The older style feet (1950 - 1963) were designed based on my 1954 Hermes Rocket (see photos), and later adjusted to universally fit older ones based on my 1938 Baby. These have been installed on quite a few machines since then without any issues.
There are two different styles of Hermes Baby/Rocket feet. The older machines use small round feet, which I offer in either black or gray depending on your taste. Later machines starting in about 1963 use completely different rectangular feet that require hardware both inside and outside the machine to install, be sure you have your screws, rectangular washers, and internal threaded clips that the screw must mate with.
The older round feet (Choose "Midnight Black" or "Steel Gray") must push through about 8-9mm holes in the bottom and use no screws. Depending on your machine, installation can be a little more finnicky, but if you push one edge in first, then twist while pushing down, then hold it there while pushing in the bulging part and pushing down, rinse and repeat...eventually it goes in, and stays in! By the way, I did this without removing the case bottom. Getting the old decayed rubber out required a tweezers and patience, that was harder than installation.
The newer rectangular feet ("Late Model Black") are very easy to install as long as the threaded clips inside the machine aren't loose or missing--be sure to not bang the machine around once you remove the screws on the feet. In fact, please replace these one at a time, just remove the screw, remove the metal washer from inside the old foot, place the washer and then screw into the new foot, place the foot on the machine and screw it in place. Simple.
These are improved feet using modern 3D Printing techniques and materials, I think they look and function better than the original rubber ever could have, and will hopefully last a lot longer! On my machine, and every single machine I saw in photos, the original feet had decayed into thin brittle uselessness, these replacements should cushion typing and grip the table very well.
Please look closely at the photos to be sure these will fit your machine. The foot design looks simple but has extremely tight tolerances. The case is less than 1mm thick, and the original feet were about 2mm thick inside and outside, and on my machine with the metal machine frame resting directly on the inside of the feet (and felt). You can't really 3D print this thin shape, so I came up with this design (see photos) with a flat bulb on top which you can pretty easily squeeze through the hole, and then it expands to grip the hole and stay put. It is taller than 2mm inside, but hollow, so the machine can compress it to mount perfectly, suspended on the hollow bulbs like shock absorbers.
For the older machines, you *may* need to remove the machine from the case to install the feet. If so, just remove the obvious screws around the outside perimeter, then lift it out (it may seem stuck in place, but that's just the old feet sticking to the frame). They seem like they won't fit, but as long as the holes are about 8-9mm they will, the trick is to sort of screw it clockwise pushing in, keep pushing, and then reverse directions once or twice and it should pop right in. The bottom shape is designed to resist getting pulled back out again accidentally.
I designed these to be nearly an identical replacement, but with the advantages of modern technology we can engineer materials that were previously impossible. I printed with NinjaFlex Gray TPU (https://ninjatek.com/ninjaflex/), which is nearly indestructible in ordinary use (but a knife or scissors will cut it, just like rubber!), flexible, and pretty gripping on most surfaces. I printed these with a complex infill (with a variable gyroid and hollow fill structure) for a balance between good friction on the table, tight fit on the machine and shock absorption. These look and function much like the original, but should last much longer and be far more durable. Some people may prefer the original dull rubber look, but I actually think these have superior look and performance compared to rubber.
I designed these for my own Hermes Rocket. This continues my experiment to see if it's worth my time to make some more for the community.
PS: Ebay's volume discount display is a bit confusing, each purchase is a SET OF FOUR feet in the selected color, so picking "1" is one set of 4; "2" is 2 sets of 4 (8), etc.
** PSS: Typewriter and other props not included! No other screws or mounting hardware are needed and are not included.
