Description
Op1 inspired shape like the original by zoroseerus, but using Rapoo Gen 2 PCB. I used VT1 standard internals. But it should work with any Gen 2 mice (same PCB) with 11 cm encoder or shorter, so most of the lineup. Side button PCBs should be the same but I cannot confirm.
Top / hump variants
- Op1
- X2H medium
- Duckbill
- Np01s Ergo (experimental)
Bottom and side variants
- Op1
- Np01s ergo

This is a good platform to build more tops with different shaped humps. Feel free to remix and upload so we have more variety of shapes we can quickly swap between. Switch holder can be used to test the click feel with just the shell and two mechanical switches.
