About this 3D model
This is an EVA Extruder based on a wade plastic extruder and that use a hot glue gun heater and his 12mm diameter stick (8mm on study). It fits instead of a wade extruder on a prusa mendel. With this I could extrude soft part made of EVA. This design is still on modification, stay tuned. BE CAREFULL : the hot gun heater is plugged on 220V, prefer using your hot-end heater/controller block.
