SWMBO sister brought along a broken hinge from a cooler, good object to try out this and that to design the 3D model. In order not to overtax my brain I used SU. Now what I'm waiting for is that spool of white nylon.
Finally watched the step-by-step video to split the scale and presently printing the first half in PLA to see what "surprises" are in store. 8-| :-o

As expected the surprise was a given.
First print is on the right, with parts missing under the sloping top. That's the back half.

But the front half is even more interesting. In essence it's back to the drawing board to get the model right.
The caps on the two vents are also to be redone. Today is another snow day in the Valley, just right for this kind of "job".

BTW slowly it's dawning on me that Fusion360 is too much for my purposes and the learning curve is way too steep for this old guy. Just reading the manual makes my head spin.

Coming along nicely, HJ. I admire your willingness to jump in to this technology because as you say it can be overwhelming--it certainly is for me.
One thing I noticed that my son does more of now is to break his projects into smaller pieces that fit together later. He used to try to make something all at once but has realized he's better off breaking it down into more manageable designs/parts.

That's what I'll try next if getting the model right fails at the print stage. X( At the moment i'm not sure if it's the model or the slicer or ....

Yep, printing smaller assemblies. That "should be" bullet proof. :|

The base

With two locater points to slide in the slot of the upper portion, this in order to snug part of the upper to the side of the lower.

Six days on after flipping the upper body this way and that way I should get a good print today. Oh yeah I also completed the missing do-dads before starting the new print. Learned a few more tricks while doing that, like making an elliptical shield for the front of the upper body.
One by one with lots of "fun". 8-| 8-|

And then there was a little surprise .... the LowerBody print would run perfectly until it got to the bulge on the backside (29mm) then it took a jump of 14.5mm (top end of the bulge) and continued printing in midair.
Took a while to get that sorted. :-o :-?

Now I can get cracking with the vents, the roof and other do-dads that will be needed.

How is the battle going?
Well the present print of the upper section is called F2, will be nice to get there.
The wonks would call it "a tremendous learning opportunity". =)) =))
