Robo R1/+ v6 Hotend (Round) Mount and dual fan shrouds

thingiverse

This is a custom version of @TechSupportGo's dual fan mount for the Robo R1, which houses a V6 hotend with a round design. It also features a velocity stack at both the front and rear to enhance airflow from the fan to cool the heat sink. To match this setup, I've paired it with @sysadrift's revised rear fan mount for the R1+. Please note that you might need to perform slight filing using a round file due to the printer's dimensional accuracy. I highly recommend printing all the pieces or at least the fan shrouds in materials with higher melting temperatures (such as ABS, PC, etc.) to prevent them from melting through after use. To get the most out of the fans' velocity stack, print at low layer heights greater than 0.1mm. Also, it's advisable to move the X-axis to -90 degrees while printing on the velocity stack side down, using low layer heights to avoid needing supports.
