Meticulously chosen products!
"Ratz" are a fun print that can become quite addictive. it's all
to easy to end up with a 'RATZ' infested house. There are two
options provided. The 'Biting RATZ' file opens the mouth when you
left the tail and, printed well (with 3 shells / 50% infill or
more), has a good bite!
The "Ratz" file is a static model with no moving parts. This file
can be printed with 2 shells and 10 - 15% infill as it doesn't
need the strength required for the 'Biting RATZ' file to make it
springy and strong.
At standard size "Ratz" are approx. 85mm tall. They print great in
PLA on Makerbot's (as the images show). They should print well in
PLA on most well set up accurate machines. However, the design use
extreme angles that will be a challenge for ABS. Please also note
that some slicing apps and machines may find the fine tolerances /
angles / detail challenging. No support required.
"Ratz" are fun! if you print one you'll end up printing lots. The
designs have been test printed lots of times to refine them so get
started and infest your house / office / car with some 'RATZ'.

would be no way to clear it out and it would not move as
If you lift the tail and the mouth doesn't open immediately
wriggle the tail and mouth gently to free them. Adequate clearance
has been allowed for most machines / slicing apps but others may
need a little movement to free these parts up.
