Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4009736. A simple backpack concept for mounting a bltouch probe/PINDA and an air-pump for part-cooling to an E3D Hemera extruder. The bracket can be printed on FDM, but I recommend FormLabs High Temp Resin for the ducts. There are 2 duct options, one for a standard v6 block and one for the larger volcano block. Required parts: 3x M3 bolts 3x #4 screws Airline tubing (https://www.amazon.com/gp/product/B0002AQI9K)
