I'm so glad you didn't take offence at my last post , I really am grateful and I was worried you might take it the wrong way but I often feel with people you've never met you need to set a base line to the conversation like this .

That's cool , it will be a while before I start thinking about gears although a gearbox case is not too far ahead of me .

When making an exportable STL file it shows a wire frame of how the shape is built up of faceted triangles and you can tell from there that a serious amount of number crunching is going on , its no great surprise that when it starts to animate multiple gears meshing that it gets hot under the collar but so far I've only experienced one issue of unexpected behaviour , I tried to delete a component from a sketch and suddenly half the object disappeared ? I had to backtrack a bit to get around it , i assumed it was my error but I'm not so sure now

These are some more 834b bits , rear trailing arms , i wanted to make some slightly longer ones for my runner , the black one is just a 1/1 test print with no detail , one of the white ones is a copy of the original but slightly strengthened in the cross brace ribs and the one with DADIO on it is 5 mm longer and constructed differently , I'm printing the long one now in what i hope will be a fairly finished design , the 1/1 copy needs a couple of revisions before i share that either but the pictures show where I'm going .

That's some really nice work. Looks great!

Following your advice i fitted the longer trailing arm to the rear of my runner 834b as a tester printed in draft , very nice fit , only revised one thing and that's to incorporate the washer that's fitted at the front pivot into the design of the arm , this will widen the arm at the pivot and hopefully reduce play at the joint ,i increased it from 10 mm to 12 mm wide so a 20% increase , I have another printing now with this addition and I'll give it a gentle run , I have some PET-G coming so as a final part I'll try it in that material , hopefully the dimensions won't change too much .

I have to say, Dadio, for someone who was completely new to 3D modeling and printing just a few days ago, you appear to be picking this up rather quickly. Those parts shown above are VERY nice!!

I'm more than a little jealous.

I have a lath and mill so I'm used to thinking I 3d and also drawing up designs , I'm also dyslexic and I think that help in these situations .once you get a handle on the software its not that hard just a big initial hill to climb .
