Anyone using a Bowden extruder on their Mendel. I am working on customizing http://www.thingiverse.com/thing:16523 for a single extruder and the parts I have on hand. The biggest issue is that it uses Sketchup, and the resulting model is not manifold and thus I can’t modify it in OpenSCAD. Therefore, I’m rolling my own parts from scratch. I want to move the mass off the X slide which I noticed is able to twist (causing the hotend to rotate to the back on fast travels) a bit due to how the extruder motor hangs off. Anyway, if someone has a working version, I’m happy to be inspired by it
Have you tried the http://cloud.netfabb.com trick to repair the STL? About every STL Ive seen from Sketchup needs repaired. Once you do that itll more often than not import to OpenSCAD. I clicked on one of the files and had it processed through netfabb… it had 6 holes and 5 shells at 236k before and after it has 0 holes, 1 shell, and sits at 44k. Lesson: process all SKP files before working with them.
I did not try the cloud version. I tried Netfabb Studio Basic. I gave up, tried Meshlab, gave up after two nights and rolled my own. http://www.thingiverse.com/thing:41336
Netfabb studio basic doesn’t perform as many options as the cloud version does. For anyone that sees this. NSB is great, but largely limited.
http://cloud.netfabb.com did work on this file.
I still prefer starting with OpenSCAD and allowing parametric modification of a thing.
@Jay_Couture Sure absolutely, OpenSCAD FTW. It just sounded like you were trying to import a file from SKP and were having problems is all.
Yes import the stl exported from Sketchup so I could performe some CSG operations to change the retainer nut diameter.
