Thanks Paul. The wheels are from soldered 0.35mm dia tinned copper wire. They are just a star of horizontally taped wires soldered in one iron application to a vertical wire inserted into a tiny drilled hole in an MDF board. The vents are solid styrene rod of two diameters glued as a tee then sanded etc to simulate a vent. The oars are 0.5mm styrene rod glued to blade shaped strips from 0.25mm styrene then shaped with a knife. Not that good but at a distance quite effective.
Funny you mentioned the vacuum cleaner. I am always dropping tiny components on the floor and unable to find them. I dropped one of the launch railings and could not spot it so used the vacuum cleaner to cover the whole area. Found it in the Dyson slightly bent but usable.
