This custom spool‑end stopper was designed for the Creality SparkX I7, combining eerie artistry with precise engineering. The centerpiece is a melted skull‑heart motif, sculpted to look as if it’s dripping over the spool’s edge — a perfect fusion of horror and charm that turns a simple filament reel into a statement piece.
Created using Tinkercad and refined with caliper‑measured accuracy, the slot fit was modeled to slide snugly onto the spool end, ensuring a secure hold without adhesives or friction damage. The design balances aesthetic flow with mechanical precision, making it both decorative and practical.
Printed in dual‑tone PLA — deep crimson fading into mossy green — the finish evokes a molten, organic texture that catches light beautifully. The heart’s contours and skull recesses pop under directional lighting, giving the illusion of movement as the spool rotates.
Perfect for makers who love mixing dark fantasy with functional design, this piece adds personality to your SparkX I7 setup — proof that even a spool cover can have soul (and skull).
