This is a sort of wire frame pumpkin I designed based on a similar one I saw made of plywood at a local Home Sense last year.
I originally drew it to cut on a laser cutter, but I haven't finished building mine yet, so scaled it down and printed it instead.
I have included the Sketchup file that also has a 'plate' of parts laid out for cutting on a laser cutter.
The parts will push together, but since they are only 3mm thick, they ideally need holding together with glue (I used superglue).
