I frequently tote my Prusa i3 MK3 around, and the frame is a little harsh on the hands with all the weight underneath it. This is a slip fit handle that slides under the frame to add some curvature that makes it easier to carry. I designed it to come on and off easily so that it doesn't take away valuable print height.
Approximately four hour print on a Prusa i3 MK3 when sliced at 0.2mm @ 20% infill with 2 perimiters using the gyroid infill pattern.
Print in the default orientation, no supports needed.
