Hi folks!  As part of a new project I found myself needing some "civilian" wheels for an M10 ammo trailer, and for want of AM parts I designed my own!  If you need some they can be printed off from Shapeways.com, at this link:

They are 1:35 scale, cored for a 1.6mm axle (Evergreen 1/16" rod), with HW ("Highway tread") tyres modelled on Goodyear examples.  They even come with brake drums!




Regards,
Tom
