RichRap's 3DR - BIGGER Top and Bottom Extensions

Inspired by Pablogil - I've modelled up some even BIGGERER(!) Extensions to RichRaps wonderful 3DR.
**As used in http://www.thingiverse.com/thing:203893!**
(Blatant self plug)

These should be printable on any standard sized RepRap bed (190mmX190mm) and will increase the cylindrical print volume of the 3DR to 'about' 260mm Diameter (assuming you increase your rod lengths appropriately)

Included is a 3D model of a fully assembled 3DR frame, for easy visual reference of where these fit.
