Add Body.stl, Wheels.stl and Rims.stl

Try to resize Body part. UI will hang.

[ioquatix]

Just adding Body.stl and scaling to 30% gives the following

Illegal division by zero at /usr/share/perl5/vendor_perl/Slic3r/GUI/3DScene.pm line 379.
Perl exited with active threads:
	1 running and unjoined
	0 finished and unjoined
	0 running and detached

Turn off background processing. Also, see #3589 and #3591 (merge the changes from the PR to get a workaround for the divide-by-zero).

[ioquatix]

Awesome. So should we close this issue?

[lordofhyphens]

Also probably related to #3499. It can be closed, just as soon as I find something else to reference (as there's two issues here, both of which are duplicates of something else).

[lordofhyphens]

Going to close, the former is related to Perl threads (which will go away once we replace the GUI) interacting badly with libslic3r, latter has a workaround (and has been reported elsewhere).

Great, thanks :)
