Enhanced X-Carriage for TAZ printers

This new fancy X-carriage works as an easy replacement for TAZ X-carriages! It possesses additional support, but also a back plate on to which you can mount things like cameras, lasers, or probes! The holes are set up for M3 screws and thermal inserts, with the exception of the three main screws that mount the back plate to the carriage, which are M5 screws and M5 thermal inserts.
