I've had the Studebaker Champion/Commander 3D file in my bookmarks for four pc/laptops now 
(After much googling I'm pretty sure this one is the Champion). When I got my 3D printer (Ender3 Pro) in January it was time to buy the .stl files...Pinshape thought differently and isn't selling files at the moment...other means were sought, I eventually aquired the files and once I got in touch with the the files original owner I sent him payment as it's the right thing to do. Now I'm free to post pics.
The original scale size body was my first body print and did that flat on the printer bed, hence the circles on the top curved surfaces but an eyecatching design on the bonnet (hood). I wondered if I could NSR'ise the body in Cura (the slicing software) and it was super easy but the lights are now race shaped which I actually like. This body was printed at a 50° angle on the printer bed which took much longer (23 hours) but should need less body prep.
Once that was done I designed a chassis for it in Fusion 360 which I started using a few weeks ago, I've not done any 3D CAD before but plenty of 2D. Motor is an NSR Shark 20K geared 11/32 with 10mm Ultragrips on Mitoos solid alloys. It goes well!!!...and is my favourite car.
I've been using a centre pivot like that with SlotIt pods for a couple of years. Since that pic was taken I've designed a sidewinder and inline chassis with built in pod and rear suspension but still with the centre hinge. Although each one was supposedly the 'final' version I keep coming up with improvements. The BMW and Manta have a flexible front end as well as rear end, this means the body can tilt independently of the wheels...I'm not convinced of any advantage on a flat track and much extra hassles so have ditched the idea...for now
The bodyshells all sit on the chassis on the outer sills and for holding them on I've used tape inside the bodyshells for all these, a strip stuck face-on-face with another at one end with the sticky side stuck to the inside of the body and the other end under the chassis...it works well
(I don't like body posts and screws but am designing a couple of alternative methods of mounting the body).
We do a lot of Slot Rally in the club so have plenty of Rally cars with the circuit racers.
The cars from back then left:
MSC Ford RS200 - 3D printed Studebaker Champion - Fly BMW M1 - Sloter Opel Manta 400 - NSR Corvette C7R - Team Slot Renault Alpine A310 V6 - SCX Fiat Abarth 124
The RS200 was my first 3D chassis, very flexible, SlotIt inline pod and 4WD pulleys designed initially in two pieces to fit the wheel hub as there's not enough room for axle mounted ones, then replaced with one piece versions...it goes well and has lead outer ballast like the other chassis.
The Stude...I love it...I'll finish it one day when I stop designing and printing chassis for my other bodyshells.
BMW M1, my first flexy chassis design and just for kicks I added front flex too, it's a Rally car, it'll be OK and goes great, much better than the original Fly podded chassis.
Opel Manta 400, these are a bag of **** from Sloter but the body makes a passable version of this 80's Rally icon and now goes MUCH better than before this has a different design flexy front end.
Corvette C7R, these already go well, this body was found in a bag of slot car discards, snapped in half behind the rear window and was resurrected with superglue & bicarb powder then bodged onto a Scaleauto chassis as I thought it was the Scaleauto version but isn't, then added a SlotIt sidewinder pod, it went well and I'm expecting this version to also when it's finished.
Alpine A310 V6, this has been round the block, used to go surprisingly well as a standard car until it was reclassified as an Open Class car due to the motor mount (someone called it an adjustable pod, it's not what I'd call adjustable, in fact mine was glued in solid with lead over the top). Against other established cars this didn't stand a chance, the body has been on a scratchbuilt brass chassis in the past but it's been sat waiting for over a year and should go well with it's new sidewinder chassis.
Abarth 124, not much bigger than a Mini and the standard car is good in it's class but as an Open class car this should be miles better. This is my first inline design, yes you guessed it I've thought of new improvements since it was printed on Friday.
Although I like tape for the body I need a better option for speedy body removal, I need to draw up some kind of jig to sit bodyshells on to accurately measure the bottom edge of the body and at the same time wheelbase. I'm thinking two tubes the body will sit on and automatically set the correct wheelbase and a calibrated wedge to measure body sill height much like an RC droop gauge.
