I got a 3D printer around Christmas time and have been playing around with it quite a bit. I working on printing a chassis and dirt late model body in 1/43. I designed a couple different versions of the chassis, one using a standard 1/32 size can motor (tight fit!), and one using an ff-030 GO! type motor. Here is where I'm struggling (my background is 1/32, so forgive me if some of these questions about what parts to use sound silly, I'm a 1/43 newb):
What wheels (brand and size) do most of you use when scratch building? The smallest ones I have found are the slot.it sipa33 wheels, but there is not much in the way of tire selection for them. I would like to use hubless wheels (like the CB design) if possible. For tires I would like to use urethane tires around 17-18mm diameter but can't seem to find any of those either.
For the ff-030 motor, where can I find inline gears (pinions and crowns)? Or are you just using standard 1/32 gears (for a 3/32 axle)?
