5-29-15 Added all the stl files you will need. I modified the bracket to fit the Pico head better. I tested and the front fan mount is not necessary to run filament, but it does help keep barrel cool. 4-18-15 Added another part to the make mod. Changed thing:447903 to mount 50mm fan blowing air out from hot end side. Gives you a push pull fan system. Keeps everything cool including the stepper motor. 4-27-15 Just made a V2. Works much better. Has a much shorter distance to push air past Hot end. Yes it works great! Pico Hot end in a Divinci 1.0 Using - thing:707530 and a modified thing:620454 No problems with the thermistor readings or temps. It's spot on. I used 123D Design and MeshMixer to make my changes.Followed the instructions for Thing 707530 and changed Thing 620454 to fit in the Divinci carriage. I add bearings to the tension wheel. I used the original Davinci 5Volt fan not the Pico 12 volt. It prints so nice now. No problems with PLA or ABS. The Pico hot end is a work of art. I am running Repetier firmware on a Hackintosh system. I did have to file down the E3d V6 parts for a better fit. No problems with the thermistor readings or temps. It's spot on. Give this mod a go when your ready. You won't be disappointed with the results.
