N2 Printhead CAD Model

Postby pmb » Sun May 20, 2018 3:44 am

Hello All,
I am wondering if anyone has an accurate CAD model of the N2 Printhead (preferably the double extruder but single is fine as well). Prefer an open format (STEP, IGES, etc.) or Solidworks.

If nobody has one I will put one together and post it here.

Regards,
pmb

There is one on Thingverse, but it onle has .stl files. I was able to import it into Soidworks to work with somewhat, but if you have the time and inclination to put together a model in a better format, I, for one, would be very grateful.

I have a reasonably accurate drawing in Sketchup - which isn't ideal as a software but it works (for free).

If you contact me I would email it to you - it won't attach to the post as its "not an acceptable file type"

I could also export it as a few different things but the free Sketchup is a little thin.

Fusion 360 will import the file as a mesh and allow some conversions (I usually do real parts in 360)

For various reasons, to actually create detailed drawings in Sketchup, you need to work in a large scale during drawing - I usually draw parts 100x or 1000x normal - its only an issue when drawing and editing - not in the saved object - so I scale things back down to real size as the last step. I have the head as a 100x file.

It has my modified heat shields, modified fan ducts and my periscope extruder camera on it but those are easily hidden or deleted.

detroitus and Mark,
Thank you for your responses. I plan to do some modifications to my machine, so I ended up building my own CAD model.

Disclaimers:
1.) The model is based off of measurements using a caliper (I believe it is quite accurate - Raise seemed to base everything on millimeter or half millimeter increments)
2.) My printer was delivered in April 2018 and all measurements come only from it
3.) I have the Bondtech extruder modeled (not the stock Raise3D)
4.) Tapped holes are modeled based on the major diameter of the screw i.e. 3MM tapped hole is modeled as a 3MM hole.

The step file he shared opened in Solidworks without any problems for me. You just need to import it as an assembly.
