# A RepRap Mendel variant using sheets for the frame instead of rods
|
|
|
|
## Standard variants
|
|
[dibond](https://github.com/nophead/Mendel90/tree/master/dibond) is the version that was sold as a kit with 3mm sheets, 8mm rods and uses nuts and machine screws through the frame.
|
|
|
|
[sturdy](https://github.com/nophead/Mendel90/tree/master/sturdy) is 12mm MDF sheets, 10mm rods and uses wood screws into pilot holes in the frame. It can be built without CNC.
|
|
|
|
[mendel](https://github.com/nophead/Mendel90/tree/master/mendel) is 6mm acrylic sheets with a 10mm acrylic base, 8mm rods and uses machine screws into tapped holes in the frame.
|
|
|
|
[huxley](https://github.com/nophead/Mendel90/tree/master/huxley) is a scaled down version of dibond using 6mm rods and NEMA14 motors.
|
|
|
|
The dibond, sturdy and mendel versions can be modified to accept the E3D v6 hot end. The files that change are [dibond_E3D](https://github.com/nophead/Mendel90/tree/master/dibond_E3D)
|
|
and [sturdy_E3D](https://github.com/nophead/Mendel90/tree/master/sturdy_E3D).
|
|
|
|
## Limitations
|
|
The dibond and sturdy versions are well tested and popular. The acrylic version, called mendel, hasn't been built for a long time and is not recommened.
|
|
The Huxley version hasn't been tested in its final form although one prototype has been made of an earlier version and a few snags fixed since.
|
|
|
|
## Use
|
|
Add the directory of the OpenScad executable to your search path. OpenSCAD-2015.05 or later is required.
|
|
To get PDF versions of the sheet drawings add InkScape to your search path.
|
|
|
|
To make all the files for a machine run
|
|
```python
|
|
make_machine.py machine_name
|
|
```
|
|
|
|
To make just the bom, sheets or stls run bom.py, sheets.py or stls.py machine\_name.
|
|
|
|
machine\_name can be dibond, mendel, sturdy or huxley. To make your own variant copy scad\conf\mendel\_config.scad or scad\conf\sturdy\_config.scad to yourname\_config.scad. Then run `make_machine.py yourname`.
|
|
|
|
To view the model of the whole machine, open scad\main.scad. It will take several minutes to render (about about 5 minutes on my computer) but after that you can pan and zoom it at reasonable speed and changes takes less time to render. (Note: main.scad will only render correctly if conf\machine.scad exists, which is created by the make_machine.py script.)
|
|
|
|
To view a sub-assembly, open the individual scad files. Set the exploded flag in config.scad to make exploded views.
|
|
|
|
To get blender renders of all the parts put blender in your search path and run `render.py machine_name`.
