Cooling Duct for Colido 2.0

thingiverse

The Colido 2.0 is a decent machine but it lacks effective cooling - at least in my model. A built-in fan cools the mounting bar with a heat sink, the motor somewhat and the electronics via air exiting the left side of the heat sink. However, most of this air is wasted by being directed to the right from the heat sink, leaving none near the components. This duct replaces the heat sink entirely. Now, the bar and electronics are air-cooled with most of the air circulating around the nozzle. The motor receives little cooling, but I'm hoping that's okay - after long prints, it doesn't feel hot and most steppers work fine even when very hot. If you're reading this, feel free to ask me if any problems have arisen subsequently. This duct is significantly lighter at 10g than the heat sink, which weighed 19g. To fit the duct, the head assembly must be partially disassembled. Here's how: 1. Remove the electronics cover and the spring for the filament loading lever. 2. Unplug the motor. 3. Remove screws from the fan and take away the motor and heat sink. 4. Remove the two screws holding the bar to the frame from underneath. After that, it should be a straightforward fit, and you can reassemble everything. Note: Due to the cooling effect on the nozzle, you'll need to increase your nozzle temperature setting.
