Customizable tray V2

This is a new version of what used to be the customizable part of this thing: http://www.thingiverse.com/thing:1702685

It is a tray that can be customized for a lot of uses. It includes options for holes or not, special ventilation fins for soaps and an optional customizable tube mount that lets you click it on to any tube between 6 and 40 mm.

So go ahead and make your perfect soap tray, a beer holder for your camping chair, a perforated drip plate or a simple but perfectly sized box.
