Ceiling/Desk Light Enclosed Diffused Shade

We needed a couple of shades for the hall so I've come up with this ribbed design shade, we didn't want anything too bright so I designed in an end cap as well, this is a push fit, and removable for bulb changes etc. the cap is optional of course.This shade is only suitable for LED low energy bulbs.I listed as a ceiling lamp shade but would work equally as well with desktop lamps, the center opening fixing point of the shade is 30mm.I've printed with Bambulab PET-G Translucent filament which acts as a diffuser as well.The shades have turned out really well and look great in the Hall.Thanks for Looking
