Cat base for the IKEA SVALLET lamp shade. https://www.ikea.com/cz/cs/p/svallet-pracovni-lampa-tmave-seda-bila-70358487/
I only offer the base, the lamp needs to be bought at IKEA for $4 and just assembled.
The finished lamp is 340mm x 250mm x 130mm
The test print was on more parts than the finished model actually is, sorry for the photo
