Thank you so much for sharing this!

So far I am 2-for-13 with my 3D printer, in terms of getting things successfully printed. But I am learning!

For this heatsink thing: https://www.thingiverse.com/thing:2184834

...it doesn't print because it tries to put some material in mid-air when it gets to that second flange from the bottom. But I think if the two pieces could be split up and rotated 90 degrees, it would work. (Maybe it would be tipsy from being tall and thin but I don't know).

I am looking for a free, entry-level program to try to edit these things but haven't found one yet. TinkerCAD doesn't seem to allow you to "cut", and it looks like Fusion360 is a paid product, which I'm not quite ready for that level of commitment yet, given my batting average with the printer.

Anyways I'll keep trying stuff, it's been fun so far!
