Extruder for Mendel with "complete" documentation
Status: fully working (v 2.3)
Be patient please, page is under (permanent) construction.
This page describes the my extruder for RepRap Mendel. Several months im trying to complete my reprap 3D printer. After many tries, this is what i have now.
1. its relativelly easy to build
2. cheap
3. modular (0.3 0.4 and 0.5mm nozzle)
4. designed in ISO standard
I´ll upload 3d models in Allibre format, 2d drawings in .pdf format (for machined, handmade parts) and stl models (for printed parts).
Special thanks to wades/gregs extruder (accesible version) and Mk6 hotend designed by Makerbot and many others.
Before we start, lets have some preview.
complete extruder Allibre model v1
Completed extruder w/o nema stepper and nozzle.
complete extruder Allibre model v1.1
Upper part (geared/cold end) is similar for all my versions.

File:Zemciko wader printed parts.7z STL models from Allibre. Printed parts for v1 and v1.1 extruder.
Geared end is redesigned Greg-Wader version with some modifications.
FE simulations
FE test v 1.5 (modular brass hot end with PTFE tube)
FE test v 2.1 (Al hot end with PTFE main body)
Tests
First clear print (0,35mm nozzle) hotend v 2.3.
Features/Bugs
Size of holes for nylock nuts in main extruder body should be decreased. (nuts are slipping and must be fixed)
