Additional Spool Holder

I wanted to be able to have 2 spools ready in case I wanted to do a colour swap part way through my prints. So I added another Spool Holder but, the filament detector was only in a good position for a left or right hand spool. I decided to use the cranked spool holder and that worked better. I decided if I created more space between the spool and the filament detector that would resolve the issue. While creating more space I made the spool holders a little fatter as this seem to reduce the tension on the filament while printing.
Its not pretty but its practical.
comments please.
