SummaryHi, I have made a compact support for prusa extruder, the idea was to adapt a direct j-head for use with bowden. This support is more compact than standard, and to do this I have re- designed the braket to fix It. The braket is manually made, cutting and drilling a standard 3x5mm aluminium bar (are sufficient: a file, a saw and a drill... :) ). To complete the project I have made this airtripper extruder: http://www.thingiverse.com/thing:1055201Print SettingsPrinter Brand: RepRapPrinter: PRUSA I3 r2Rafts: Doesn't MatterSupports: Doesn't MatterResolution: 0.2Infill: 25%Notes: The material, I used PET-G printed at 235°C, bad at 80°C and speed 50%, z-hoop 0.2mm retract 6mm
