Ceiling Light Shade

This two shade ceiling fixture works with those cheap, two-bulb fixtures you see in a lot of bedrooms without ceiling fans. I was tired of looking at the bare bulbs so I put this together.

I designed in two shades to keep the prints small enough for tiny beds and all parts are designed to be printed without supports or brims.

Depending on the length of the ceiling to the mount base at the bottom you may need to slice a bit from the top of the shroud model in your slicer, or simply use without the shroud, all it does is cover the ugly metal fixture anyways.

Disclaimer: I should probably note that even using compact fluorescent bulbs instead of LED bulbs may be too hot for your filament, my shades are holding up fine with CFLs but yours may not... I would never recommend incandescent bulbs though, they just put off way to much heat! Also, LED bulbs are common place now, cost a tenth of the price in electricity, and put off almost no heat... I love the future!

Print Settings

Printer:

Prusa i3 MK2.5

Rafts:

No

Notes:

Rotate models with the larger flat sides to the print bed before printing, supports are not required, Fusion 360 outputs my STLs in this orientation for some reason.

I printed the shades with a color swap at 89mm, using Prusa ColorPrint. The thought was the darker color wouldn't allow light to pass through it and would hide the thicker part where the connector inserts into the shade, this silver filament was not opaque enough, keep that in mind.

I used 3 walls to make sure the 2mm thin walls of the shades printed with no infill and just walls (I think infill wouldn't look great with light shining through it).

Both shades, the connector piece and the shroud were a total of 14 print hours.
