This roll paper holder is a vertical storage solution specially designed for kitchen baking and cooking scenarios. Crafted from eye‑catching green plastic, it features an integrated base paired with four parallel cylindrical tubes—each precisely tailored to accommodate standard baking paper, silicone‑coated parchment paper, and aluminum foil rolls. The holder can be securely mounted on the inside of a cabinet door using screws through the backplate or with adhesive mounting strips (as shown in Figure 1), cleverly leveraging otherwise underutilized vertical space. The four rolls are arranged in a stepped configuration, ensuring smooth, uninterrupted access to each roll; circular viewing windows on the side of each tube provide a clear, at-a-glance view of remaining paper levels. Against the backdrop of beige cabinet doors and gray marble flooring, this holder transforms a cluttered stack of four kitchen paper rolls into a neatly organized, color‑coordinated display.

Design Highlights

• Independent Anti‑Interference System for All Four Tubes

  The four cylindrical tubes are arranged in a stepped, parallel configuration, with optimized spacing that ensures effortless, non‑interfering simultaneous retrieval. Each tube is equipped with a pull‑guide groove along its outer surface to prevent paper tears during extraction.

• Invisible Storage Logic for Cabinet Doors

  Installed on the inside of cabinet doors (as shown in Figure 1), the holder discreetly disappears when the door is closed yet remains readily accessible when opened—perfectly addressing the challenge of limited countertop space in small kitchens.

• Visualized Remaining Paper Indicator

  Each tube features a circular observation window on its side, allowing users to quickly assess paper levels without having to fully unroll the paper (as illustrated by the small hole design on the tube’s side in Figure 2).

• Anti‑Slip, Damping Design

  The inner walls of the tubes are adorned with subtle, spiral grooves that provide just the right amount of friction to keep the paper rolls from loosening under gravity while still ensuring smooth, effortless pulling.

Technical Specifications

• Compatible Roll Core: Standard 25mm inner diameter for common baking paper, silicone‑coated parchment paper, and aluminum foil rolls.
• Recommended Materials: Food‑grade ABS or PP (oil‑resistant and easy to wipe clean).
• Structural Details: Total width approximately 28 cm; individual tube length 20 cm; observation window diameter 12 mm.
• Printing Tips: For optimal results, print the cylindrical tubes in a vertical orientation to ensure smooth inner walls; the base should be printed with 100% infill to maximize load‑bearing capacity.

Application Scenarios

▸ Storage for baking essentials inside kitchen cabinet doors (e.g., white baking paper, transparent silicone‑coated parchment paper, and silver aluminum foil—as shown in Figure 1).

▸ Organized storage for craft paper and wrapping paper within study cabinet doors.

▸ A dedicated storage solution for rolled blueprints and engineering drawings in the workshop.

▸ Compact storage for rolled facial tissues and cling film inside bathroom mirror cabinets.
