Push-in Screw / Hole Cover Caps — Parametric (3D Print)

FREE parametric PUSH-IN COVER CAPS by MarineLab3D — snap-in caps to hide screw heads or close unused holes. Set the hole size and they click into place: no glue needed.

🔘 Christmas-tree stem with cross-slit → 4 flexible fins that snap and grip inside the hole
🟢 Head style: flat or domed, with an overlap rim that covers the hole edge cleanly
📏 Fits holes from 4 to 30 mm · head Ø always ≥ hole + 2 mm

🖨️ Print head-up, NO supports. For best snap use PETG (slightly flexible), 2-3 perimeters. PLA/ASA also fine for a tighter fit.
