This is a simple dustpan, printed in two parts:

PAN: The dustpan measures 200 (L) x 240 mm (W) x 70 mm (H), perfect for the build plate of a Prusa i3 MK3. You can scale it as you wish. I would recommend using a bed adhesive or printing with 5-10 brim outlines to keep the flat bottom of the pan from warping.

HANDLE: The handle measurse 38 mm (dia) x 100 mm (L). For ease of printing, you could print this vertically along Z axis. However, for optimal part strength you may wish to print it horizontally with supports. It is designed to be glued and press-fit into the pan cutout.
