It is a 150mm by 150mm by 200mm storage cube able to be attached to other modules and made into a unit or multiple draws in any configuration you so like. It can hold smaller items so as pens, pencils etc but is able to hold some medium items like the average phone or battery pack. Has been 3d printed and all parts work with only some minor supports on the handle to remove after printing. Around a 2-3 hour printing time per full module.
