Sander hopper for the wpl series pick up trucks 

Note…

 this is a vibration hopper you have to get a couple rumble packs out of a old controller and wire them up as a servo and it'll provide enough vibration that sand will actually come out .(dry sand)

measurements are 140mmx79mmx45mm height

I've printed a few of these without supports successfully (see print settiings)

Print settings.

.2 layer height

3 walls, 3 layers top and bottom

supports (you decide) as all printers are different but i don't
