1/10th scale
This is my take on a classic 60s sports car. It's RWD with a back mounted 540 motor.It's supposed to be able to printed without the need to paint anything, although some details as the dashboard and the seats will really pop with some paint!
The screw holes is all 2.8mm so 3mm screws fits perfectly and it's mostly 10mm screws, both flat heads and rounded heads. The rest of the parts I just glue/solder.The light buckets are 5/3mm so regular leds will fit.I use PLA for most parts but the tires are TPU 95A and Gears and axles are ABS. Transparent PLA or t-glase for the semi-transparent parts.
I use the windshield trim as a guide to cut a transparent plastic sheet to make the windshield.Exploded view in the PDF but I'm open to make a more in depth instruction if that's needed.I mount the electronics where it fits with double sided tape. You can use either a short pack or a standard nimh-size battery.
Don't hesitate to make suggestions to make it better!
