3D printed Stir Box

[kimbo]

Hi.

As we all know the buy a stir box can be very expensive, so i designed a 3D Printed stir box for the DIY'er.

I am using
12volt 3050rpm geared high torch motor
12V 3A PWM DC Motor Variable Speed Controller
Height adjustable motor

Here some pictures of the sample







The disk with the magnet doubles as a fan that blown air down to the motor and around in the box so the electronics have some flowing air. There will be more air vents down the motor in the production model.

The production model will be black and is printing as i type this, i will put some pictures up of the print a bit later. I will also post pictures of the build process after printing

Motor mount and electronics mount can be seen forming



Walls are growing and you can see the holes for the on/off switch and the power plug forming



Growing nicely











Test with pure VG



These will be made on order and should take about four to seven days to complete, shipping will be with Courier Guy

The box will go for R650 excluding the 12volt 1amp power supply and stir bar

35mm Teflon stir bar R30 (6 in stock) More on order

12volt 1amp power supply R60 (11 in stock) More on order

Shipping will be R150

@Rob Fisher That is the big reason for me being so quite. Was working very hard to get something out that will not break the bank but will be reliable

What did Henry Ford say "You can choose any color as long as it is black" (for now)

I only have a 50ml bottle and it did not have a problem with clean Dolly Vardin, you must just start it slow so the liquid get some momentum then you can increase the speed.

I will put your name down in the OP. The one printing now is for a of forum client, when it is done i will make a vid of it working, once i start working on it i will PM you the banking details
