Updated to version 1.1 thanks to /u/Forty_0ne's new base models.
Special thanks for /u/Forty_0ne on Reddit for the original scans and amphibiousParakeet and Inornate for the bottom base and cover.
This is my G305 Ultra Light base and cover. The base comes in two versions, a light version and a EZ version that is heavier but easier to print.
This modification includes an experimental ring finger pull for those using fingertip clutch styles.
