Extendable cupholder barrel

The Cupholder Barrel

The cupholder can be used with sofas or sand thanks to two different interchangeable attachments. Furthermore, the attachments can be slided in and out, so that they do not get in the way when not in use.

The assembly is very simple: you simply slide in the desired attachment, and then snap the rings onto the top and bottom. I printed the cupholder in PLA, but for added durability, I recommend printing it using stronger materials.
