UltraRigid

Introduction
====================
This started as an upgrade, now it is an entire new printer. While it is based on Hypercube evolution, and Seriously inspired on E3D Tool Changer printer, It is something else.

It is using 3x TW-04-09 from Igus and 3x TS-04-09 as linear guide. It is also compatible with MGN9 with small alterations.

The Iddlers are 2x F623ZZ mounted mirrored.

It has been designed to cut out of a 4mm aluminium sheet of 1000mm x 500mm.
