stl files for 1.75mm parts  

Re: stl files for 1.75mm parts

Hi, the 1.75mm files will be uploaded today on our website 🙂 Later I will upload the scad files on github, but they need some refactoring :-/

Thant's great to hear! Where on the website will the files be available? I'd love to start printing as soon as possible 🙂

Re: stl files for 1.75mm parts

I am also interested in where to find the designs for the parts. I found Josef's github ( https://github.com/josefprusa ) with Prusa i3 parts but they are slightly different than the ones that came with my printer kit (and I like the ones I got better :-)).

Thanks!

this should be it http://www.prusa3d.com/wp-content/uploads/prusa-i3-175-stl.zip

Re: stl files for 1.75mm parts

Thank you! I have now been able to replace the clamp holding part of my printer together. 😀

Hi.

Is the Z endstop holder missing from this batch of stl files or do I need my ears cleaned out??

Cheers

Hi Ben

I believe that it's the same as the 3mm version. That's about what I used to print a modified version.

You're a star Peter. Cheers!

Re: stl files for 1.75mm parts

Does anyone know where the OpenSCAD files for these live? I've checked out both https://github.com/josefprusa/Prusa3.git and https://github.com/josefprusa/Prusa3-vanilla.git and can't seem to find the right branch and configuration to generate these. I would really like to tweak some things and would like to start from the parts I have.

Thanks

Hi Ross

They appear to be available here: https://github.com/prusa3d/Prusa-i3-Plus

Re: stl files for 1.75mm parts

Thanks Peter for the quick reply! That is exactly what I was looking for. So happy to finally have these files!

Re: stl files for 1.75mm parts

Where can I find the stl for the original part fan? I have all the others and I have tried PJR's replacement but it blows more straight down.

It seems that the parts have been moved. I have attached the one I downloaded some time ago.

EDIT: Just checked the link in my previous post; they are there under printed parts/stl.

Yeah, I just realized after reading your post that I was looking for the wrong file name. For some reason I was thinking it was named Part_Fan.

I really liked your redesign but it just wasn't providing enough direct air below the nozzle to cool fast enough. I am having problem with curling on smaller prints and the nozzle hitting it on moves. I have tried Z-Lift which eliminates the hitting but introduces the possibility of the nozzle actually picking the very small print off the build plate. I have tried every temp on PLA from 190-220. Luckily I have patience to try and figure this out.

I am open to any suggestions.

Re: stl files for 1.75mm parts

Hi Richard

My nozzle amendments work for me, so I guess you could also make amendments which work for you...

Z lift during moves: that never worked properly for me, as it requires gravity to assist the lowering (due to thread backlash) and on my printer, the extruder tended to take a few seconds to fully lower, leaving raised plastic where it should not be!

I do believe that the next iteration of Josef's printer may address some of these issues.

I am currently in the process of building a printer with a taller print area (230mm) and have re-designed the extruder (and other parts) for the extra height.

This one is based on the Lite6 (using a V6 in my primary printer), with slightly amended plastic parts, plus a few new ones. The fan holder is very similar to the one on my clone.

Re: stl files for 1.75mm parts

I have ZERO design skills. 😥

I have been looking for a way to add a part fan to the front of the extruder housing. There just aren't many places to add one.

Re: stl files for 1.75mm parts

Well, there's the one I made, and the good news is that it allows the neater block to be installed the right way up, meaning more efficient heating.

And I have no design skill either. It is amazing just how simple tinkercad is to use.

The only minor error I made with this is that I have made the parts which hold the extruder and motor about 8mm taller than is necessary. But that's no big deal.

The only "new" part I designed was the fan bracket. Nice thing about this is that for those wishing to add a Z sensor (for "auto-levelling") is that there is a place at the right of the extruder, quite close to the nozzle.
