Upgrade your vintage Case toilet with this 3D-printed adapter bracket made from durable PETG. Designed for Case models with 7-inch hinge spacing and front-mounted bolts (including Case 1000, 1100, and 3000), it allows you to install modern Bemis and other Stay-Tite toilet seats with ease. No need to search for expensive or discontinued Case toilet seats—this practical solution restores function while preserving the look of your classic fixture. Each kit includes stainless steel hardware and raised bumpers for a stable, level fit. Order it printed in a color-matched PETG—close to original tones but not exact—or choose a neutral base to paint it yourself. Custom color options available.
