The Rebels' hovercraft from The Empire Strikes Back
Construction directions included in snowspeeder_instructions.pdf
Designed for 1/8" stuff. The benchmark square in snowspeeder_1.pdf should measure 1"x1".
The firearms are created of 1", 5/8" and 3/8" dowels. The spans do not need to be super precise, most significant is to make the centre-drilled holes (where the smaller ones fit into the larger ones) right down.
