Specifically designed for electronic soldering and DIY crafting, this wall‑mountable solder wire rack is crafted from 3D‑printed materials and features a wall‑mounting option with pre‑drilled screw holes, helping you save valuable desk space while keeping your solder wire neatly organized. The rack includes dedicated solder wire spool holders paired with wire guide channels, preventing tangles and knots for smoother, more effortless access to your solder wire.

• Wall‑mountable design: The back is equipped with pre‑drilled wall screw holes (compatible with M3/M4 screws), allowing you to securely mount the rack directly onto walls or workstation side panels—freeing up precious desk space.
• Solder wire spool fixation: The rack features a round, secure slot (with a diameter tailored to common solder wire spools, such as Φ50–Φ60mm), ensuring that spools stay firmly in place and are less likely to slip off.
• Wire‑tangle prevention: A wire guide channel runs along the bottom and sides of the rack—5mm wide and 3mm deep—to gently direct solder wire in an orderly fashion, minimizing the risk of knots and tangling.
• Customizable options: The 3D‑printed model allows you to adjust the screw hole placement (to suit different wall materials), the slot dimensions (to accommodate various solder wire spool sizes), and the color (available in black, white, or transparent).

Design Highlights

• Dual mounting options: Mount it on the wall with screws—or simply place it on your desktop thanks to its flat, stable base—offering flexible installation to fit a variety of workspaces.
• Anti‑slip & smooth operation: The solder wire spool slots feature anti‑slip textures (enhanced friction through 3D‑printed layer patterns), while the wire guide channels ensure smooth wire routing with minimal resistance and no risk of kinking or knotting when pulling the wire.
• Precise screw hole placement: The screw holes on the back are precisely spaced and sized—for example, a 30mm × 40mm hole pitch and a 3.5mm hole diameter—making them compatible with most wall anchors and self‑tapping screws.
• Lightweight yet durable: Crafted from PETG, this 3D‑printed rack is lightweight (approximately 50g) and boasts a temperature tolerance of up to 60°C, remaining dimensionally stable even after prolonged use.

Technical Specifications

• Solder wire spool diameter compatibility: Φ50–Φ60mm (customizable up to Φ70mm)
• Screw hole specifications: Φ3.5mm (compatible with M3/M4 screws), with a hole spacing of 30mm × 40mm (adjustable as needed)
• Wire guide channel dimensions: 5mm wide, 3mm deep, with a length matching the rack’s width (approximately 80mm)
• Recommended materials: PETG (high temperature resistance and excellent bend resilience), ABS (high strength and superior impact resistance)
• Printing recommendations: Use a 0.2mm nozzle, set the infill to 30% (for enhanced structural integrity), and add anti‑slip textures to the inner surfaces of the slots (such as diagonal or dot patterns). For the screw holes, consider applying countersunk recesses to prevent screws from protruding.

Application Scenarios

▸ Electronics Workshops: Install the rack on the wall next to your soldering station—solder wire is always within easy reach, keeping your workbench tidy and clutter‑free.

▸ DIY Crafting Areas: Perfect for maker spaces or model‑building stations, this rack helps organize multiple spools of solder wire, eliminating tangles and making storage more efficient.

▸ Repair Stations: Ideal for mobile phone or computer repair workstations, the wall‑mounted solder wire rack keeps your supplies neatly stored, boosting workflow efficiency and reducing downtime.

3D‑Printed Model Instructions (Optional)

• Model File: Available in STL format, compatible with slicing software such as Cura and PrusaSlicer.
• Customization: Easily tailor the model to your specific needs by adjusting parameters like screw hole placement, slot diameter, or wire guide channel dimensions.
• Printing Settings: We recommend a layer height of 0.2mm, an infill density of 30%, and 3 outer shell layers with 2 inner shell layers to ensure both structural strength and a smooth, polished surface.
