Better Y carriage belt holder block for Geeetech Prusa i3 Pro B Aluminium

The Prusa i3 Pro B Y Carriage Belt Holder Replacement. The existing design has some flaws but a clever solution is possible. I chuckled when advised to "drill a hole in the belt and then insert a screw through it". Clearly, this was not designed with longevity in mind, and as expected, it snapped after just two weeks.\nI discovered that the replacement belt was significantly thicker than the original. Fortunately, this design has been created using OpenScad, making it easy to customize for other carriages with similar needs. To install the new holder, you will require 2 x M3 screws approximately 18mm long and 2 x M3 nuts (my kits had some extras lying around).\nIt also includes profiles for various belts based on designs from Thingiverse:\nthttp://www.thingiverse.com/thing:16627 by Droftarts\nhttp://www.thingiverse.com/thing:19758 by doommeister
