DIY 3d Printed Sous Vide Water Circulator

I decided to build a sous-vide from scratch due to high import taxes here in Brazil and due to difference in materials available here.

1. Immersion heater - Link
2. Extension cord - Link
3. Temperature Controller 110/220v Thermostat W3230 - Link
4. 12v power supply - Link
5. 12v water pump
6. Tri-polar ceramic connector - Link
7. 3d printer with ABS filament
8. 1 hexagonal head screw for the support
9. 8 small screws

I ended up deciding to use ABS due to its relatively high melting point and due to one of the supports actually being immersed in water.

I cut the wall plug from the immersion heater and the extension cords and then connected everything in the following manner.

The important thing is that the 12v supply and the pump connected to it will always be turned on in order to ensure water circulation at all times.

The heating element will have to be controlled by the thermostat, so when it reaches the desired temperature it will stop.

The picture is actually from my V1 but the idea is the same.

Make sure you place the water pump in a way that does not suck water from the plastic box and overheat/damage.
