Create a perfect-fit stand for a model

[Cadie107]

Hello!

I have recently 3D printed the 3D structure of a protein which I wanted to gift to a colleague who submitted her thesis about it. For that, I intended to print a stand, which I tried to design, that it perfectly fits the model.

My current approach for that is the following:

1. Extrude a stand (solid body) and place the protein (mesh->object) above it.

2. Lower the Protein in 1 mm steps and cut (combine tool) it out of the stand.

This method comes with 3 problems:

1. It's not perfect - some smaller artifacts which block the insertion can still remain.

2. It's perfect - there is no offset between the object and the cut. When I try to offset 5000+ faces, my Fusion 360 crashes.

3. It's tedious! 😉

So I wanted to ask, if anyone knows a way to better solve this issue of removing the overhanging regions in a mould.

I'll attach a screenshot as soon as my Fusion 360 comes back from freezing again (:

Thanks for every advice

That would be my way of doing it.

If I could make a Grasshopper script to do it, it would be wonderful.

Meanwhile, I tried this in IV2010, which was a bad idea.

The reason is b/c you have to have 100 WorkSurfaces @ 0.1mm spacing, a 2dSketch on each WS, Projected profiles in each 2dSketch (they are very intricate and some have overlapping geometry), and then Extrude/Cuts for every profile.

It's way over the top for the quantity of work involved.
