So, I'm trying to make some small knobs with my 3D printer. I made a cylinder, and a second one perpendicular to the first. I moved it to overlap the top edge, then selected all and intersected the selections
When I deleted the perpendicular cylinder, it leaves the curve i wanted on the top, but there were some leftover spikes I can't delete. When I exported to .stl and loaded into my slicing software the spikes were there.

can someone tell me how to remove these?

Thanks!
