I created a very simple 3D model in SketchUp Free for Web. It’s basically a sheet with some thickness and 9 holes I created with the push/pull tool. See screenshot below.
In the next step, I exported the model into an STL file for 3D printing. See STL file here.
In the last step, I uploaded the STL file to 3D Hubs, but their manufacturability analysis revealed 15 intersecting faces! See screenshot of wireframe with failed checks highlighted in red here.
I tried converting my 3D model in SketchUp Free for Web into a solid group as well as creating the same shape in 15 different ways, but the manufacturability analysis still fails.
Despite my best efforts to research the issue, I cannot figure out why my SketchUp model isn’t 3D printable.
How can I create the shape shown in the above screenshot in SketchUp Free for Web such that it’s 3D printable? Which steps do I have to go through in SketchUp?
Any insights and advice are highly appreciated, since I’m working on a stainless steel enclosure for the pilot of out fireplace, and I would love to get the Fireplace going before it gets cold.
Thank you very much,
