This super awesome looking banana lamp is not easy to print but the result is, in my opinion, definitely worth it.

I have been working on this model for months, trying to make it printable, I've tried various slicers and supports but most didn't work. This is why I added the fixed walls to the model to support the overhangs. With the walls the model prints without any additional support and results in the cleanest overhangs. After printing the walls can be cut off and with some sanding, what's left over, is barely noticeable.

I added three models of the banana peel, one without the walls (if you find a way to print it with support I'd love to hear what support you used), one with narrow walls (for 0.4 nozzle) and one with wider walls (for 0.6 nozzle).

I printed the vonoroi inside without any support.

The hole inside the banana peel fits a basic E14 lamp socket. I used a small LED refrigerator lamp as a light source.

Good luck printing and please upload your result :)

On someone's request I added a solid inside, I made both a completely solid one to print in vase-mode and one with a 1mm thick wall. I haven't printed these so I don't know what it'll look like, so if you print them please upload pictures :)
