Monoprice Select Mini ABS and PLA air duct

thingiverse

-=UPDATE=-\nI've shifted my focus to other projects and have updated the last version I created along with the .123d design file to simplify modification for anyone who wants to.\nThe current build still has a few kinks, such as the PLA vent being approximately 1cm too long and tolerances that are a bit too tight. \nI've designed an air duct for the Monoprice Mini that clips on and features two bottom plates that slide into place. One is a block off plate for use with ABS, while the other is a vent duct specifically for use with PLA.\nThe design is currently in the works.\n-=UPDATE=-\nThere are only a few minor issues with the design. \n1) After printing, the bottom plates fit a bit too snugly. These can be sanded down to make them fit more easily. I'm redesigning them to have looser tolerances.\n2) The mounting points are 4mm lower than they should be. Although this is not a major issue, it means the duct doesn't cover the heat sink properly. In the next revision, these will be moved up.\n3) The tabs that snap onto the carriage are a hair too thick. Once again, they can be shaved down after printing to make them fit. In the next revision, I'll thin them down.
