About this 3D model

A new size guide for Royal Mail letters and parcels, including a third slot for the new _Small Parcel_ category. This guide has: * Measuring slots for width and height * Outline profiles for width and length * Coverage of _Letter_, _Large Letter_ and _Small Parcel_ * Price guides by weight, as of May 2013 * A handy ruler Great for eBay sellers, or anyone sending lots of variously-sized parcels.. There are two drawings included here: a three slot version and a two slot version, for those with smaller lasers, or who just need the letter sizes. For most of us, letters are either "Put a stamp on it" or "Take it to the Post Office", so we really just need those small "stampable" slots.
