Wanhao Duplicator 4 / 4x Filament Tube Holder
This is a modified Tube Holder for the Wanhao Duplicator 4 / 4x from http://www.thingiverse.com/thing:409297
Just a simple bracket to bring the filament tubes outwards for easier use, and to prevent the filament from slipping off the spool and getting tangled between it and the machine. It also utilizes the stock filament tube holders for easy installation!
