Introduction
The RepRap Haeckel is an open source 3D printer that uses fused deposition modeling (FDM).
Ernst Heinrich Philipp August Haeckel (* 16. February 1834, † 9. August 1919) was a German biologist who promoted and popularized Charles Darwin's work in Germany.
The Reprap Haeckel is based on a generic Mendel. Its goal is to be a self contained unit, that can easily be upgrade to have a Heated Build Chamber. The idea is to have a very rigid frame and x assembly that can withstand light milling, such as PCB Milling or wood engraving. The Haeckel has two integrated spool holder, each holds up to 4 filament spools (9cm wide each).

Frame Parts
Quantity | Length | Part Type | Used Where | Comment | Looks like | 2 | 550mm | 20x20mm aluminum extrusion | back struts. The spool holders get attached to these, depending on your filament spool diameter, you might want to use longer back struts. | 2 | 420mm | 20x20mm aluminum extrusion | front struts | 12 | 430mm | 20x20mm aluminum extrusion | rest of the frame | 2 | 270mm | 20x20mm aluminum extrusion | spool holders. can be extended or shortened | 2 | 90mm | 20x20mm aluminum extrusion | Needed for x end and x idler. Soon to be available fully printed. Minimum length is 90mm. Can be up to 410mm (not recommended). |

Smooth rods
Part | Used Where | Quantity | Length. | Comment | Looks like | X-smooth rods | 2 | 370mm | Can without problems be longer than recommended minimum lengths. Length shouldnt exceed 390mm. | Y-smooth rods | 2 | 430mm | These lengths can not be longer. 5mm shorter will still be okay, but 1mm longer can not be mounted | Z-smooth rods | 4 | 370mm | Can without problems be longer than recommended minimum lengths.Length shouldnt exceed 390mm |

Front Frame Assembly
This chapter shows how to assemble the front rectangle of the Haeckel's frame. You'll need:
- 2x 420mm Extrusions
- 3x 430mm Extrusions
- 1x y_motor_mount.stl
- 2x y_rod_clamp.stl
- 2x three_way_connector
- 2x corner_small.stl
- 2x corner.stl
1. Overview | 2. Begin by sliding a three way connector on a 420mm extrusion | 3. Slide the connector down and tighten it | 4. Take a small corner and attach it | 5. Take a second small corner and attach it to the other side. Repeat Steps 2 - 5. You should now have two of these front struts. | 6. Attach one 430mm Extrusion to one of the three way connectors. Attach Y-Motor mount and two bar clamps as pictured. | 7. Attach the other strut to the horizontal bar. Make sure the Motormount and bar clamps are correctly attached. You will not be able to insert nuts into the t-slot afterwards | 8. Take two 430mm extrusions and attach them to the top and bottom corners. The motor mount gets attatched to the bottom extrusion | 9. Make sure the frame is rectangular. The measurements can differ by the type of extrusion you are using. This measurement is 470mm and needs to be exact on all points | 3. The distance between the lower extrusions needs to be 50mm (center to center). For 20mm wide extrusions its 70mm (outside to outside) | 3. The front side of the Haeckel is now done and square |
