Filament tube holder with filter chamber

This is a expanded version made by Paul4x4design. This moves the filament guide tubes out to the middle of the spools. In the lower chamber, it is designed to house a filter to clean the filament as it is pulled through.

The small pillars need to be reduced to 6mm from 7mm. Also, the top filament side still need to be reamed out a smidge to properly hold the guide tubes. When I get a chance I'll update the drawings.
