Screwdriver Holder for IKEA HEJNE Shelves

thingiverse

This is a corner-mounted screwdriver holder designed to fit seamlessly into an IKEA HEJNE shelf unit; see the attached image for precise fit details. I have included the Fusion 360 `.f3d` file for any necessary adjustments, as I envision a few tweaks to enhance its functionality. These ideas are outlined at the end of this document. # Installation **Note:** This design assumes your shelves are assembled with supports positioned at their outermost extent; in other words, configured for multiple banks of shelves. Refer to the installation photos for clarification; if your support overlaps the shelf due to outside hole usage, you'll need to modify this design. Required components: * 1x M3x20mm bolt * 1x M3 square nut * 1x M3 washer Step-by-Step Instructions: 1. Drill a 3mm hole through the center of the shelf inset; consult the design and images for precise details. 2. Remove the bolt securing the shelf (ensure all items are cleared from the shelf beforehand). 3. Insert a M3 square nut into the slot on the bottom of the holder, working against gravity to secure it in place. If necessary, use a weak tool or adhesive like glue to hold it firmly in position. 4. Place the holder and attach it using the M3x20mm bolt (and washer), which should pass through the shelf, into the holder, and tighten securely into the M3 square nut until the shelf bolt hole aligns with the part's hole. 5. Replace the shelf bolt, allowing it to pass through the holder. # Improvements While this design meets my needs for now, there are opportunities for improvement: * Moving the slot for the square nut to the side would eliminate the need to fight gravity during installation; a clear oversight on my part, but one that worked out in practice. * Tapering the screwdriver holes could provide added stability when holding tools.
