With halloween right around the corned, I wanted to design a new car and theme it accordingly. I took inspiration in Hotwheels' "Bone Shaker", and came up with this gorgeous Hot Rod!

As my previous design, it uses a piece of filament as axles, since printing them at such a scale was not an option (see video on preparing the wheels). But if you'd like to print it bigger, of course, a filament won't do, so I did include printable axles for use at bigger scales, I tested 150% and 200% and works like a charm.

As always, my designs are comprised of multiple parts to mix and match colors as desired.  I even included variations. You may chose between printing shutted windows, or the interior details. Also you can print a non-halloween version with a regular front grill and headlights. And, of course, the jack-o-lanter is optional.

Easy print, without supports (well, this time there's one piece that uses support, I included a version with custom supports integrated in the model) Easy and satisfying assembly, no glue required at all.

The model is for a 1:64 scale, same size as most diecast car toys such as hotwheels, matchbox, etc.

3D printing settings

The files should position the parts in the correct orientation when placed in the slicer.

• 0.2 layer height
• 2 perimeters
• 15-100% Infill (more weight make it faster on tracks)

Look for included 3mf file. They were made on orca slicer, with an Ender 3 profile. Each part is on a different bed, already positioned and with the same settings I printed with.

Recommendations

• Try using classic perimeter generator instead of arachne, I got better results for the body at least.
• Use adaptive layer height on the body for smoother results
• The rims should press fit, but they're a bit tricky to get right, use XY contour compensation in your slicer to find the right fit. They are really fast to print ;)
