Help designing for 3D print please
Hey guys, I'm pretty new to designing and just started watching some tutorials. Can anyone guide me on how you would go about designing this please?
I made the center with a simple rounded corner rectangle and thickness/pocket tools, but I have no idea how to go about adding the rounded edges. I tried creating arched sketches on different planes but I have no idea how to curve them between the planes.
I also tried just creating flat surfaces to create an "L" shape and then round of the corners thinking I could extrude the edges, but can't figure out how to bend them.
I thought this would be a simple design to learn on, but it seems harder than I originally thought. Any guidance on how to go about it please? I feel like I may be overlooking some simple method and trying to go about a way of doing it that's not the best.
Any tips would be really appreciated!
