This file is for share in total OPEN SOURCE our long research & development over the customization of the Delta WASP family 3D printers made in Italy (www.wasproject.it). We project this puller/extruder case to fit one All Metal E3D V6 extruder and one E3D Titan Puller - www.e3donline.com
With this case you can construct by yourself one complete direct extruder ALL METAL with the BEST QUALITY on the market.
You need 2 30x30 mm fans too: one is for the heatbreak of the j-head and one is for refreshing the printing area.
All the stuff works perfectly with a simple RAMPS 1.4 and a good ARDUINO Mega 2560.
Actually we are in progress with a new update of this project. Let's get in touch.
