My hometown has no Ikea store (yet). Ordering this single tray would cost more for shipping than its cost, so I decided to design my own and 3D print it.
Printing instructions:
Material: PLA or PETG (most likely any would work)
Layer height: 0.2 or less
Nozzle size: 0.4 or 0.6 (both work well with Arachne perimeter generator)
