Replicator 2X cooling tube holder

This is a DIY guide to set up print cooling using an aquarium air pump (such as http://www.amazon.com/Hydrofarm-Air-Pump-Outlets-7-8L/dp/B002TCC46U/ref=zg_bs_2975471011_7) and some 3mm silicone tubing. You get instant, targeted blasts of cool air at the print nozzle by using this method, which prevents warpage from occurring when you print large models. This setup makes it easy to create small parts with intricate details that might otherwise end up as messy ABS blobs. Just attach a single tube or point two tubes towards the left or right extruder if you're working in dual extrusion mode. You can even make your own Y-tube connection to handle the tubing. Using print cooling makes printing small parts and detailing them easier by ensuring warpage is not a concern when it comes time to removing support structures. To achieve optimal results, print with low layer heights of 0.1mm or 0.15mm, use at least two solid layers for each printed object (also known as the shell), and include around ±30% infill during your printing process. Note that this guide has been optimized to work effectively using ABS, but it might also work when used with PLA, although you'll have to run some trials first. If possible, you should use your slicer settings in order to set the object as lying on its back or in any other way needed depending on your needs for print orientation so that it doesn't need any supports at all.
