Ratz

"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'.

Print Settings

Notes:
Easy print in PLA on a machine will a filament fan... but there

are extreme angles and fine tolerances that may be a challenge for

some machines and slicing apps as well as ABS. They print really

well on MakerBot's as shown in the images provided.

No support is required... leave it turned "OFF" to make sure

support doesn't the biting up inside the biting type as there

would be no way to clear it out and it would not move as

expected..

Post-Printing
Biting RATZ

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.
