Shopvac CNC Vacuum Shoe System

thingiverse

CNC shopvac vacuum shoe system is designed for certain popular models of Chinese-made CNC (3040T, 3020T). It is designed to be used with the small-size shopvac. I design this around the CNC I own which has slots along side of the spindle mount. I use those slots as a way to attach the vacuum system to the spindle. Mounting it this way allows me to easily adjusting the height by sliding it up/down. But, if you have different type of spindle mount, you can probably derive you own way of mounting this. The design consists of 3 basic printed parts. You will need to get an additional part from the craft store: a sheet of thin-flexible foam. Cut the foam sheet to form a skirt and glue it around the spindle shoe. You should be able to figure the whole thing out by looking at the attached pictures.
