Make Your Own Stir Plate: 3D Printed Stir Plate Magnet Mounting-Thingy!

In my quest to build a stir plate using a computer cooling type fan, I found that the most difficult part of getting that to work well was mounting the magnets properly. I settled on two magnets and in spite of several attempts I was unable to get an efficient (or even stable) mount for the magnets. Magnet alignment is an important part of stir plate design. Uneven or mis-spaced magnets mean easily thrown stir bars and poor performance.

I decided to design and print a 3D printed mounting aid to make magnet mounting easier and more precise. I’ve since dubbed this the HBF Stir Plate Mounting-Thingy. In my opinion, it turned out pretty amazing.

3D Printed 6ml Measuring Cup for Measuring Star San

I think 3D Printing has a bunch of possible applications for homebrewing. From tap handles to stir plates to… custom sized measuring cups and on and on.

I stumbled across these customizable measuring cups by wstein on thingiverse. The author provides files for several sizes of cups and also includes the ability to customize these to the specific size you’re looking for. See below for links to both the original STL files and a customized 6 ml version. I thought this would be handy to create a purpose sized measuring cup for Star San.

First, some background… I use the Spray Bottle Method for sanitizing. With that technique you measure out 6 mls of Star San and combine with 1 Gallon of water. Then you use a Spray Bottle to soak and sanitize surfaces. Check out of full description of the method including math for the 6 mls.

On to the measuring cup…

Printing on my XYZprinting Da Vinci 1.0 3D Printer

Completed 6 ml measuring cup. This is small and didn’t take long to print. I didn’t record the exact time, but maybe… 20 minutes or so.

Here’s the measuring cup next to a 12 cc Syringe

Here is a picture of 6 mls in the cup. I’d say it’s pretty close.

The cup affixes nicely on the side of a bottle of PBW using a rubber band.

I’d like to come up with a two ended measuring spoon. One side would be 6 ml for Star San and the other side one ounce for both Star San and PBW. The 6 ml side would just be for Star San where the one could be used for either Star San or PBW. Dosing for Star San = 1 ounce per 5 gallons and dosing for PBW = 1 to 3 ounces per gallon. If you are a design whiz and come up with such a thing, Email Us, and I’ll share your file. Otherwise, this will have to wait for me to learn Solidworks.

3D Printed Pub Style Tap Handle

3D Printed Tap Handles!

A while back I got an XYZprinting Da Vinci 3D Printer. I think 3D Printing has a bunch of possible applications for homebrewing. From tap handles to stir plates and on and on.

Note that the 3D printer featured in this post out of production.

Here’s a look at a 3D printed Pub Style Tap Handle designed by “InfiniTTTy” and available on thingiverse. A link to the STL files and project description can be found below.

I printed this on my XYZprinting Da Vinci 1.0 3D Printer. Here’s a look toward the beginning of the process. Note that my printer is out of production. See: Amazon Best Sellers in 3D Printers for current models
