New RepRap Extruder Design
Although we used our RepRaps a lot in recent times we have not done too much reprap research recently. This is about to change!
Because I want to try out the PLA Adrian sent us (thanks!) I need a new extruder which I want to build with parts I have available here. We use RB-35 motors because they are cheaply available here but they have a different mount than the steppers which are used in the ingenious Mendel extruder design which I used as inspiration. But I changed the way the insulator part is mounted since I like our T-slot mount very much. It is very stable and I don't want to glue the insulator like in the Mendel design since I'd like to be able to take it apart.
As you can see in the screenshot I model the extruder in OpenSCAD openscad.org. OpenSCAD is a very cool parametric solid 3D CAD modeller. If you like programming and 3D printing you should have a look at OpenSCAD since it is more like writing code than juggling triangles and vertices like in Blender.
