Heater Stand for PTC Heater

I designed this to get my PTC heater up off of the  heated enclosure floor to allow airflow for the fan. Printed in ASA. No supports. 

The heater I used was this: Constant temperature Electric fan heater PTC fan Auto heater Small space heater incubator(12V 150W)

Most of those heaters look similar in dimensions, so I would think this will probably work for many of them. It's nothing special, but works great for it's purpose.
