Modular Ribbed Shoe Shelf Insert

What it's for

A freestanding shelf insert for a 260 × 300 mm wardrobe compartment, sized for children's shoes. It stands on the shelf below with no drilling and no fasteners. The deck is a light ribbed grid in four staggered panels. Each panel fits a small printer bed.

Dimensions

• Assembled deck: 258 × 290 mm, 10 mm deep, top surface 130 mm above the floor.
• Deck panels ×4, brick-bond layout so no point has four panels meeting:
  • Front left: 150 × 145 mm
  • Front right: 108 × 145 mm
  • Back left: 108 × 145 mm
  • Back right: 150 × 145 mm
• Legs ×4: 28 × 28 mm foot, 20 mm cross-section post, 120 mm tall, plus a 12 mm square locating peg that is 10 mm long.
• Dovetail keys ×4: bow-tie shape, 24 × 11 mm, 9.6 mm thick.
• Estimated material: about 130–140 cm³ in total. That is roughly 85–95 cm³ for the deck, 45 cm³ for the legs and 2 cm³ for the keys.

Assembly

• Drop a bow-tie key into the paired pockets across each seam. There are 0.2 mm clearances per side.
• Press each leg peg into the socket in its corner of the deck.
• Each leg sits in a different panel, and the peg sockets stop the deck sliding or racking.
• Add felt or a thin TPU pad under the feet if desired.

Print notes

• Print every part flat or upright with no supports, using PLA and a 0.4 mm nozzle.
• Keep the legs peg-up.

Remix ideas

• Add a front lip to stop shoes sliding out.
• Swap the cross-section legs for taller ones to suit other compartments.
• Make the ribs denser for heavier loads.
