I received some good feedback on the way I approached this design and decided to add an addition tutorial to make one of these suggestions.

Yet another great tutorial. Showing how to go back through existing designs timelines to make changes was very helpful. Thank you.

Thanks Brendan!

You do great work, thanks! Greg

Thanks Greg! So do you!

Now I see the tear drop, its just heavily filleted triangle.

[@hanslain9729]

Brilliant solution. Thanks!

[@DesktopMakes]

Thanks!

I'd agree with @shentharo about having the triangle point up, but often I'll go with a hexagonal shape. If it's printed "point up" you get a nice, low angle slope to a point and straight sides. All easily printed. If printed with a flat top, usually easy to bridge. Also, it's close enough to "round" that it can subsitute for a straight through hole. For the ultimate you could even change the very bottom of the peg to match the profile of the hole (make it hexagonal to).

I ended up changing the direction of the triangle and make it point upwards. It's towards the end of the video where I show how to edit your design without breaking your timeline.

[@shentharo]

No need for a bridge if its printed flipped.

[@DesktopMakes]

Yeah, I end up flipping the triangle towards the end of the video and show how to do it without breaking your design.

What you say is all true for 3D printing, but if an entrepreneur comes along later with more dollars than sense and wants to buy a million of them, then you have to redesign it again with a circle because it will be easier and cheaper to mass-produce. 😊

Ill happily redesign for a million bucks

[@DesktopMakes]

Yes, very true. The design approach will look very different with 3D printing vs machining vs injection molding.

You make things look so easy.... 😢

Thanks but why are you crying?
