Printable Fillets

I made a custom feature to easily implement printable fillets, aka fillets that have a slightly sharper transition to the faces than a standard tangential fillet, to enable more accurate 3D printing. This is my first attempt at something like this, and constructive feedback is very welcome. https://cad.onshape.com/documents/643eceb32d9650249dd16a3e/w/78be64c6d1a48ea091dd93cb/e/16321f49c31ef6b8038a0f53

    Nice job! And welcome to the FS club 😎

    The code looks pretty clean, well documented with comments too.

    Feedback: As far as the feature itself goes, it's pretty good. Not sure I would change much.
    Something to note, the default Fillet tool can already do conic fillets which will give you the same result i think?

    Thank you for being so gracious while telling me I have recreated an existing feature πŸ˜‚. When i started the process I had a rounded chamfer in mind, and then iterated towards the conic radius, forgetting it was easy to implement in other ways. Never mind, good practice!

    All of us FS devs have unintentionally re-created an already existing feature at one point or another. I think I've done it a few times. Its just so hard to find custom features, even for experienced users.

    @janna_deeble685 When I read the thread title I thought you were headed here with it, which might still be a decent custom feature! I used the chamfer to control the max overhang angle, then rounded it off.

    My team would get some use out of a "chamlet" feature. They keep doing the chamfer and fillet step manually and manually playing with the dimensions every time, it should just be one feature.

    I don't know why, but "chamlet" feels like it should be Old English… π”œπ”ˆ π”’π”π”‡π”ˆ β„­β„Œπ”„π”π”π”ˆπ”—

    I would expect something like this for a Chamlet definition:
    Overhang angle and Fillet Radius definition…

    Personally I prefer the cleaner look of a circular profile that gets truncated like @EvanReese's example. In woodworking I think they call it a thumbnail profile? Stacking a fillet and chamfer like the method you show tends to look overly tall to me.

    5 axis 3d printing will fix this. πŸ˜‰
