Six Christmas glass-rim ornaments: bauble, tree, candy cane, gingerbread, Santa hat and snowflake. Adjustable 44–60 mm artwork, 0.7–3.2 mm rim thickness and 0–45° wall-angle compensation. Integral PETG spring jaws and a five-coupon fit-test mode. Prints flat without supports, using 2–4 colours per ornament or a single-colour STL. Print matching coupons first, then check a complete ornament on your actual glass without force. Physical grip and compatibility with strongly curved or rolled rims have not been verified.
Fit gauge: five matching spring coupons. Dots 1–5 mean −0.2/−0.1/0/+0.1/+0.2 mm adjustment. Start with five dots; never force onto glass.
Nominal upright artwork height; angled clip may extend beyond it.
Measured rim/wall thickness normal to glass near the contact zone. Default is a research-based prototype, not universal fit.
Local wall flare from vertical, viewed radially. Compensates artwork relative to straight jaws; fit-test the actual glass.
Additional slot clearance selected using the five-coupon fit test. Start loose; never force onto glass.
