About the Model
This design transforms your standard pump cap into a playful, modular centerpiece. The rectangular LEGO pad fits perfectly on the outer cap of most AIO pump covers (like Cooler Master Elite Liquid Series). It’s designed for easy assembly and personalization.
Assembly Steps
Print the LEGO pad using PLA or PETG for the best surface finish.
Clean the pump cap surface — remove dust or oil for strong adhesion.
Apply adhesive (cyanoacrylate or double-sided thermal tape) evenly across the pad’s underside.
Align carefully — the pad should sit flush with the cap’s top curvature.
Press firmly for 30–60 seconds to secure.
Optional: Add a LEGO minifigure or decorative brick for flair.
Result: A sleek, 3D-printed pump cap that’s both functional and fun — perfect for builders who want their PC to show personality.
