This beautiful snail lamp by toolmoon prints great if you are confident in your bridging and overhangs. It can be printed with no supports however I thought I'd add a little in a few spots under the base (to prevent some small stringing at 2 specific bridge points), and a spot under the shell shade at one of the harder angles just in case. Left it mostly up to the quality of cooling so that the result is cleaner without support material roughing any surfaces. There's also a raft on the shade since its very thin and not much touches the bed. Its recommended, but you can also turn this off if you choose.
The shade is printed at 100% infill but the base is only 10%. There are two little snap in links that hold the shade to the base on the plate with the base as well. LEDs or a tBulb B can be used, I'm sure most people have something laying around that'll work though.
