Cobbllebot Vertical Mounted dual extruder

This is a remix of my first cobblebot dual extruders. They are based off my first design so the front fan mount will work with the previous ones. Every part uses a m3 screw and support are built in. Support are not need but add in brim will help. v3a has 6mm hole for zip ties and wire management and is designed to be mounted on top is not necessary. Its possible to use two v3b in place of the V3a. Bothrequire a 15-20mm m3 screw to mount v3c. V3c the oval shaped hole should be on the bottom half
