IKEA FRIHULT One-gang box adapter

IKEA FRIHULT wall/ceiling connector is smaller than a normal circular one-gang box/junction box. I designed this adapter that fits a normal box and then you can attach IKEA FRIHULT to it.

• Print material: PETG for strength and water-resistant. 
• Infil: 65 to 75% for strengh
• Two M3 NUTS based on the screws of the lamp

The adapter is designed in open-scad, it's easy to make changes on it.
