Desk Lamp Diffuser

I needed a better way to light my models for product photography, and I don't have the budget or even more the space for a real softbox. So I modeled this snap-on adapter for a simple desk lamp and it's working really well!Few details:inner diameter of the lamp is 162.5mm, which should fit the standard TERTIAL lamp from IKEA (mine is a clone, but I measured one at Ikea and that should be pretty similar – I'm not that sure). There is a test print, to check if it fits and snaps firmly.
