Casio G-Shock GBA800 Chapter / index ring

thingiverse

Chapter rings for Casio GShock GBA800. I own a blackout version of this watch and the original chapter ring was extremely hard to read. This replacement index ring has made it super legible now. Warning: To replace the chapter ring, you must remove the crystal, which requires skills and specialized tools. Do it at your own risk or ask a professional watchmaker to do it for you. The original chapter ring features additional extrusions at the bottom for alignment. I intentionally omitted this detail in my design to make printing easier, but it's crucial that you handle the installation with care to ensure the indexes are aligned correctly. The fit is loose, and if you want to tighten it or adjust the print to your specific printer, a scad file is provided. I printed it on a Prusa MK2, and it fits easily, although there are some noticeable gaps between the indexes and the ring.
