r/MouseModding

This mod from tj exclusives comes in at 42 grams on my op1 8k which is a substantial drop in weight, when it originally weighed in at 51 grams. The only problem I had with this mod is the shipping time it took around two months to get to me and I live in the United States, understand shipping times but 2 months is crazy. Other than that I would say its a good upgrade, my next upgrade is probably going to be the pmm cable.

3d printed fingertip grip shell I made for the x2 superstrike, was wondering if their would be any interest if I where to optimize the shell even more and get it professionally manufactured, and then sell it as a mod kit.

Experimental prototype I’ve been building.

It listens to stereo in-game audio and converts directional events into left/right haptic feedback directly on the mouse shell.

Current tests include footsteps, gunshots and reload sounds in FPS games.

Still very early, but I wanted to see if this concept actually feels useful in real gameplay.

Curious what mouse modders think. I'll keep posting updates as the prototype evolves.

A while back I realized I'd bought and returned more mice than I'd like to admit, just trying to figure out which shape actually fit my hand. Online reviews and shape databases helped narrow it down, but you still don't really know until you hold one. So I started 3D printing instead of buying. What I ended up with: 8 hollow shells, each modeled after one of the most common mouse shape archetypes (compact fingertip, long flat shells, palm-rests, asymmetric wedges, etc.). Each shell opens with a bayonet-style twist mechanism, and inside there's room for up to 4 weight chips (10g each, so up to +40g) to simulate heavier mice on the same shape. The idea is to isolate the two variables that matter most — geometry and weight — without buying and returning six mice to figure out your preference. Once you land on a shape you like, there's a guide (made it as a little web app, QR code on a keychain that comes with the kit) that links straight to Eloshapes filtered to the closest-matching mice currently on the market — so the result stays useful even as new mice come out. This is just a personal project, called Stratum — mostly wanted to share the idea/process. Happy to answer questions about the printing, or the bayonet mechanism if useful to anyone else trying something similar.

designed by Mysti, adapted for the Viper V2 Pro pcb by nnv-w

• based on the zeromouse blade, but with a smaller footprint and adjusted grip points
• printed in 8001 resin (clear) / pa12-s nylon (black)
• stock 300mah -> xinj 130mah
• westlab 0.2mm grip tape

The button layout:

[scroll mode] [left click] (ball) [right click] [middle click]

When "scroll mode" is held down the ball acts like a scroll wheel.

I built this custom trackball mouse to pair with my Keychron K11 Pro keyboard. The keyboard slots onto the top of the mouse and they basically stick together as one unit. My left thumb is next to the keyboard's fn key, which changes the active layer and gives me things like arrow keys under the home row. My right thumb moves the ball. Before this I had tried the Contour Design RollerMouse, and putting trackpads in front of the keyboard, but both have drawbacks that trackballs don't.

I spend most all of my time at the computer for work. The goal was to minimize moving my right hand back and forth between my keyboard and mouse, which makes my right shoulder stiff. I've been using this for about 6 months and my shoulder is almost completly normal now. Mission accomplised!

As a huge bonus, using this thing is FAST. I never leave the home row and can transition between typing and mousing with very little movement, and therefore in very little time.

The shell was modeled in Fusion and printed on my Prusia 3S. Getting the ball-holding mechanism right took a lot of trial and error, but now it's smooth and the ball doesn't fall out when turned over. You can still remove it by just pulling on the ball. The ball is from an old Logitech 570. I did a version with bearings first but they make too much noise. The final version uses ceramic balls press-fit into the printed plastic.

It's programmed with Arduino and based heavily on this: https://github.com/dkao/Kensington_Expert_Mouse_PMW3389_Arduino/blob/master/PMW3389DM-Mouse/PMW3389DM-Mouse.ino

I'm a software engineer professionally but Arduino was easier than figuring out Espressif's complicated VS code integration...

MCU is ESP32-S3 N16R8. This model has two USB C ports, one to flash firmware and the other to act as the USB HID (mouse & keyboard) device. https://www.amazon.com/dp/B0F5QCK6X5

Mouse sensor is Pixart PAW3395DM-T6QU. If I were to do this again I would pick a more supported sensor. This sensor is too new and required signing an NDA with Pixart to get the documentation, which has a key in it that's required to turn on the sensor. https://www.pixart.com/products-detail/129/PAW3395DM-T6QU

I got it on a carrier board from here: https://www.aliexpress.us/item/3256806817851445.html

If there is significant interest in the code or shell models I will package it up for Github. (minus the Pixart key)

PS I finished this right before the new Keychron trackball got announced. I sill like mine better ;)

Hi all!
I am nearly finished with a set of OP1 8k weight reduction mods, but the real buff to the mouse is looking cool. Kinda reminds me of Waizowl color ways.

~3.5g base - fixes warped stock bases, reduces weight, proper side-bracing, full stock skate support

~0.7g scroll wheel - similar shape to the stock OP1 wheel
~1g side-buttons - much less aggressive side profile, not the pointy shape of the stock OP1 side buttons.

currently a 38.0 gram final build; weighed without cable.
weight may fluctuate a bit by the time everything is finalized: I plan to sell this design both as 3D models for home FDM printing, and fully packaged modkits! :D

My first 3D design idea, created using FreeCAD software. I’d be happy if anyone wanted to try out this model and provide feedback.

I don't have a 3D printer to test this model myself.

The goal of this mouse was to make the smallest grip width and click height for this mouse. I ended up getting it about 2mm thinner, but slightly taller click height.

Im not gonna post the files here because i made multiple mistakes,(back holes are a few mm offset. The sensor sits too low so it doesnt track properly(i just stick 2 skates ontop of one of the pcb supports to raise it a bit, and the hole for the scroll wheel encoder is too small, the standoffs for the clicks are a tad off so sometimes clicks wont register) but if one of you want one ill give the files

https://cults3d.com/en/3d-model/gadget/superstrike-x2-full-endoskeleton-base-kit

first off, yes my main buttons are wired to the cables for the side buttons, i didnt have any 2x5 ribbon cable connectors laying around, this is ofc not intended, but it does work surprisingly well

it weight a grand total of 28g, would be 22 without the battery but i cant remove it because as far as hte mouse is concerned, the front is missing, this does mean i cant charge the mouse, my solution to this is to take the battery out and put it in a different mouse that can charge.

in the time that it took me to make this mod pseudoku3 actually open sourced the og kotinos files, heres the link https://github.com/pseudoku/Kotinos

my mouse was printed in sls nylon 1172 pro, and its pretty nice, super gritty which i like.

as for mistakes that i made while making it. multiple screw holes arent properly aligned. the thumb paddle is too vertical. the main clicks arent wide enough(for me theyre fine but it did mean i had to modify my grip a tad bit) and the back part of the pinky paddle is to prominent, it really forces your hand into a really aggressive almost claw grip. it also makes up and down motion with the fingers a bit weird

i will probably make v2 eventually in the future if i feel like it

a little bit of extra info, this is NOT intended to be used with a scroll wheel, it is theoretically possible, but it will be uncomfortable to reach. this mod has 0 support for side buttons. and i havent made a left handed model, if someone wants one just lmk ill make it.

the click tensioning is surpirisingly ok, rmb is litterally perfect. lmb has a little pre travel. obviously this is for my print. yours may be different. but the clicks are really light, like fuck slam clicking. your goinng to click just moving the mouse

heres the link for the v1 with all of the mistakes, if any of you want to try, the mistakes arent so major that the mouse is unusable, just minor things https://drive.google.com/drive/folders/13IMwYdCRWhhlToW6yMy7Sz_l5Z2cXace?usp=sharing
