This is an elephant pen holder. The cup part of it can hold pens and pencils while the trunk can hold your phone. I printed it at 75% scale size but it will probably work much better at full size. I printed with red hatch box filament with 10% infill, which worked fine and was quite sturdy.

I used tree supports while lying it sideways so I can get a good surface finish on the outside, but one side of the inner cup had some uneven walls. This was fine for me but if you want it to be smooth, you can make it stand upright, which means the bottom will be a bit uneven. 

I saw something like this in my friends house but it was ceramic, and though that It would be nice to print. 

This is my first 3D model I designed so it might not be that good, but I hope you enjoy!
