Anbernic RG477M Custom Shoulder Buttons

Custom Shoulder Buttons for the RG477M

I’ve designed a set of custom shoulder buttons for the RG477M. 

This project was heavily inspired by the "Better Buttons for RG477M" sold on Etsy.

Personally, I still find the "Better Buttons" version to be more aesthetic and practical, but I wanted to challenge myself to create my own as a hobby.

Since there can be slight manufacturing variances between individual devices,

 I cannot guarantee a 100% perfect fit for every unit. I am attaching the STEP files, and remixes are more than welcome!

 I went through over 50 iterations, as even a 0.1mm deviation would prevent the buttons from functioning correctly.

I did design a version that can be printed without supports, but the buttons ended up being too narrow to be practical.

I personally prefer the Nintendo-style layout, so I’ve marked the buttons as ZL and ZR.
