muesliLogitech rubber coating: 2-year lifespan.
Me: Fine, I'll do it myself!
3D-printed a new shell in soft black TPU (on gray-ish PLA supports) and it fits like a glove. Honestly feels better than the original!
DIY > decay.
Let's see how long this case holds up. I'm betting it's a lot longer than the original rubber, as TPU is a lot sturdier.
Even if it fails, it's a $0.30 print that finishes in less than 4 hours. I'll keep you posted 🥳
Jamie :h2dlaser: 
@fribbledom TPU is an indestructible super science material so I’m sure it’ll last for eternity.
Probably closer to eternity than to the longevity of the original material, yeah 😆
Cassandrich@fribbledom @jamie TPU is so vastly superior to all the garbage rubbery materials used in mass-produced plastic junk. It is indeed a supermaterial. Impervious to solvents, corrosives, oils, UV exposure, heat to 100 °C or so, mechanical damage, ...
@fribbledom @jamie Only thing that might be better here is printing a hard mold in PLA or something and casting silicone. Silicone is so nice for this sort of thing.
...and how cool would it be for Logitech to sell your differently colored and sized rubber shells for your mouse?! Purple? Softer? Bigger?
If they could still sell you a brand-new mouse every two years, they'd do it in a heartbeat.
masukomi@fribbledom i feel like maybe there’s a ploopy mouse in your future https://ploopy.co
They don’t sell replacement shells but i think there’s a model for the shell that you can 3D print one of any color or have a service do it.
Nils@masukomi Hardware and software is completly opensource, but the warranty is voided when you alter the hardware, software or firmware including flashing the firmware. Exactly my kind of humour. @fribbledom
@PraetorCreech @fribbledom i mean. That’s kinda reasonable. If I were in their shoes, I would not want to have to pay to clean up after someone did something stupid that wasn’t what I designed a thing for.
especially since this isn’t a large company that can afford to not think about how many items they have to send out because someone ran into an issue from their own stupidity/mistake .
@PraetorCreech @fribbledom Open Hardware just means "we'll give you the info on how everything works, and allow you to build on those ideas as you see fit".
That's completely separate from selling hardware. Subaru isn't going to pay to fix my engine if i try running it on pure NO2.
I STILL wouldn't expect them to pay for it if they offered detailed construction plans and a license to sell new ones I build on their ideas.
mouse reeve@fribbledom you've also made a lil jesters hat I think
Austin Godber@fribbledom I hate when that rubber gets gooey
nice solution
Feels nice when brand-new, becomes sticky within just a few weeks, dissolves after exactly 24 months of daily usage.
Hate that stuff so much. Still got my first Logitech MX Master and even my MX Performance. Both working perfectly fine after more than 10 years... except the rubber sticks to your fingers and you don't want to use them anymore.
I guess Logitech knows perfectly well what they're doing here. If it wasn't for the rubber, there's literally no reason to buy a new mouse.
lizzzzard@fribbledom @godber that soft rubber coating can be removed with 100% alcohol. Sticky mess be gone!
Source: have someone in the family who uses skincare products with urea, those dissolve that soft rubber coating really fast.
Hikarii@fribbledom this is so op
SilSte@fribbledom gibt es das STL?

MX master 3 rubber shell replacement by Rikkarlo
The MXmaster 3 mouse from Logitec is by far my favorite mouse in terms of features and ergonomics. It's covered in a terrible rubber material that degrades between 1 and 4 years and becomes sticky and oily. Logitech does not sell spare parts, and adhesive skins after a while leak stickiness from the junctions (I tried them as well).So I decided to solve the problem by myself and model a new outer shell for my mouse.This solution is the best I've tested so far (and believe me, I tested many). Since I want to fight programmed obsolescence and contribute to a world with less electronic waste, I decided to share it for free. Feel free to print it and share some pictures of the results with me.

TheConstructor (he/him)@fribbledom very nice! Does the thumb-button at the bottom still work? It's the one, that I rarely use, but I could imagine, that it needs a soft rubber shell to work
Use it hundreds of times a day to switch virtual workspaces. Works just fine with TPU, if anything the material is a bit softer than the previous rubber.

WIN!!!
And what is it with products only lasting a couple years??
I have a wireless charging motorized phone holder, and the battery has degraded to the point that the arms to hold the phone will only open and close after the car has been running for a few minutes.
Bleh. XD
Julianoë@fribbledom saving this on my note dedicated to the mouse... just in (goey) case. I've had mine for 2 years +. No goey/sticky rubber shell for now. Finger crossed.
Steinar Bang(FWIW my MX master is 3.5 years now (summer of 2022, same as the laptop I'm currently using), have hade multiple dives to the floor and is still going strong...)
antimu0n 🤘 metal lynx ♿ 🏳️🌈🏳️⚧️@fribbledom my fingertips have worn through the rubber coating on my MX Vertical but the rest of it hasn't turned sticky, and the indents actually improve the grip lol
how did you recreate the shape, 3D scan?
William@fribbledom excuse me while I spend all day dragging my fingernails back and forth across the layer lines
flumen_calculi@fribbledom really cool!!!! Good work!
Karsten@fribbledom I fixed mine by gluing on adhesive foil. Never thought about printing a whole new shell. I love it!

Tamsin Powell@fribbledom any fix for when the microswitches go? I have a shelf full of logitech trackballs with a dodgy button
I haven't experienced a faulty one in a Logitech mouse so far. I'm sure they'll eventually die, but microswitches sound easier to replace than a rubber shell.
@fribbledom I've gone through many - the marble mouses

Shut up and take my money! Meine löst sich auch auf und das nervt. Leider hab ich keinen 3d Drucker

Du kannst einen 3D Druck Service nutzen und dir das ganze aus Nylon/PA drucken lassen. Kostet rund ~7 Euro.
@fribbledom
Danke für den Tipp, das mach ich gleich. Mach ich das gummi von der Maus vorher ab? Hab ich das überlesen?

Korrekt! Ist nur an wenigen Stellen verklebt und lässt sich recht einfach entfernen.

Whch one is that? My MX Master 2S is still going strong after like 6? Years

This particular one's the MX Master 3, but I've had the same issues with the MX2, the MX1, ..., all the way back to the MX Performance.
@fribbledom
That's wild, must be some difference in sweat chemistry or whatever? Sucks that you've got bad luck with them.. But hey, a good reason for a DIY project at least

Yeah, there are usually a few factors at play with these elastomers. UV, Oils, salts, humidity, temperature etc. etc.
6 years without it disintegrating is fairly exceptional though.
@fribbledom Here's how it looks after all that time. I can still feel the slight grippy texture so I don't think it has degraded at all!
Account: Firearms@fribbledom I was wondering just who uses multi-material printers, and to what purpose. I never trusted them enough to incorporate into products. But just off-loading the scaffolding to PLA seems like a capital idea.
Once you experienced a toolchanger, there's no going back.
Mixing materials allows for geometries you wouldn't otherwise be able to print. Supports don't ruin the underside of your prints anymore. You can have fancy outer shells with the cheapest PLA for infill. Models with soft edges/corners or rigid material only where it's really needed.
Going back to a single nozzle printer feels like dial-up internet now.
Vysogota@fribbledom having logitech's plastic degrading in your hand is the bona-fide logitech experience. I'd advise you against using 3d-printed-at-home materials in contact with skin, but it can't be worse than logitech's rotting plastic...
