Need help slicing

Need help getting this part sliced. I've been messing with this for 2 days. I've tried designing it in sketchup and blender. After spending a year with sketchup only to find out it's not really good for solid objects, I just spent spent a whole week trying to learn blender only to find out it's not really good for making precision parts :/ Anyway, I can make it in sketchup but when I slice it, it closes the bushing. It's a bushing with a inset. The inset snaps onto a post. It keeps closing the inset across the whole bushing. I've had this type of problem before with other bushings. I am using Cura to slice. I've tried messing with so many options I am at my wits end. I really wish I knew someone who could teach me this stuff better. I would attach the file, but it is too large.

Also when I put it in netfab to try and fix it, netfab closes the bushing too.
Thanks.

To clean up your object, import your data file into AutoDesk MeshMixer.
Look into the free solid model CAD packages, e.g FreeCad.

Is this the )$#@#$)*@#) problem with Sketchup where it doesn't quite push holes through the outer surface at times?????

Antslake,
Can you not compress the file or upload it somewhere else with a link?

IDK, sketchup is always making holes and weird things all the time. If you don't build things perfect they won't work in a slicer, and sometimes no matter what they won't work. I spent so much time getting good at sketchup only to hit walls like this all the time. It's so time consuming to learn new programs, and sometimes the tutorials or instructions are written so poorly. I uploaded the file here, never used this service before so let me know how it works. I just spent the last 4 hours learning meshmixer.

All day to make a stupid bushing, lol still don't have it yet.

I just downloaded sketchup 2014, which I see is more geared towards makers, good. But it still doesn't make the bushing I want. Then I downloaded a plugin called CADspan, where you upload the file to them and they "fix it" for printing use. What I got back resembled a blob LOL.

Wonderful...

Holy crap, I figured it out this time. It only took like 12 hours. So sketchup doesn't like making follow me tubes in small demensions. The trick is to make the piece large, then scale it down. :/

I am still curious if there is another way of making this. Gonna start the FreeCAD tutorials this week I think.

you might want to try a plug called cleanup,

In MeshMixer there is an Analysis button, within it there is an Inspector button, and within it is an Auto-fix option.

If you're designing mechanical objects, best to use a solid modeler, it has none of the problems that a surfacing program has like Sketchup.
With a solid modeler, your model is always 100% water tight.

Can you upload the .SKP rather than the STL?

I ran the part through NetFabb and then loaded it into TinkerCad. You can see there are quite a few problems.

BTW, TinkerCad works great for this kind of Boolean stuff.

freecad is very good i have used a couple years now. lately i have been using designspark mechanical it was a little easier to learn. generally i can make a part faster in designspark it is more click and move with mouse. the downside it does not export to cad formats like step or iges but will export tosketchup. it will import step but unable to edit it.

Last week MeshMixer released a new update that lets you add your own 3D printer so you can layout and arrange a print job for your specific machine.

I did make the part in blender and had the same exact problem. I also used the autofix button and it closed the bushing off the same way cura did.

I managed to successfully print the bushing. The bushing is a replacement part that is now obsolete. It goes between the seat and frame on an ATC250R 3 wheeler. I am mak8ng a few different parts and selling them on my website www.apshobbies.com The filament is Stratum3D 12-64 nylon which is excellent btw. Going to do a write up on it soon.

not sure if you're a student or have an academic email address (university or college etc), but if you do: go to students.autodesk.com, and you can get autodesk inventor for free
