Inspired by the Zeromouse from optimum, it weighs around 30-33 grams fully assembled and comes together in mere minutes, just 25% of the mass of the original G502 Hero. It takes 9 screws from the original body and has 4 clickable switches. I would assume the weight could be dropped to sub-30 grams if someone were to desolder the remaining vestigial switches that used to be the top buttons. It is currently printed in PLA but will work with PETG, though it may be slightly heavier because of the different densities. Daughterboard for the side buttons must be removed, and it should work with the wireless versions of the G502.
Please print in 100% infill, supports on, with as many walls as you need, but at least 3; it is relatively flimsy compared to more droppable mice, even with the oversized supports for the grip. Use supports for the various screw holes dotted throughout, I used tree supports. I used PLA but PETG would be better for a mouse like this, though it is slightly more dense.
2026 UPDATE
cleaned up the Fusion file, fixed the scale and added a small attachment to replace the LR buttons on the scroll wheel. Added a few fillets so people won't cut themselves, but weight should be about the same.
UPDATE 2
Fixed the LR scroll wheel buttons, lightened it up
