Making Tune Intersections Water Tight
-
I have been working on designing a roof rack for my car and have decided it would be fun/useful to get the model 3D printed. From what I understand in order to print it I need to make sure the model is "Water Tight".
After a significant amount of effort and using the "Solid Inspector" plug-in I believe I finally managed to make the model water tight: https://dl.dropbox.com/u/84843025/SketchUp/WaterTight/Rack%20-%20WaterTight.skp
However after speaking to my local 3D printers they said the spans were a little too long and that I would need to add supports every 10mm-12mm to prevent it from sagging. Given the print platform is a little over 200mm in length I rescaled my model to be 200mm and added supports every 10mm or so. Here is a "skeleton file" of the model with supporting struts: https://dl.dropbox.com/u/84843025/SketchUp/WaterTight/Rack%20-%20Skeleton%20-%20Supports.skp
(the model will be printed upside down which is why the struts point "up")But when I go over all the "bones" in the skeleton with tube I keep getting holes and I just can't work out how to get rid of them: https://dl.dropbox.com/u/84843025/SketchUp/WaterTight/Rack%20-%20Leaking.skp
I have spent pretty much my whole day trying to sought this out but just can't work out how to plug them. If anyone here would be able to direct me on a good way to fix up these holes I'd be most great full.
All the best,

Try to scale your model up by 10 or even 100 times, fix the holes and scale it back. SU has problems with creatingtiny geometry although when this geometry is already created and scaled down, it can support existing geometry.

I've been working on a number of small parts and that trick has made a huge differences in getting clean results. What I've done is draw the set up for making the part, make it a component, then copy it. Scale it up, finish building the part in the larger version, save the file, and then delete the larger component. It's worked every time so far.
