Mug Stabilizr

STABILIZ THAT MUG

Got a tall, narrow insulated mug that you are worried about knocking over? Don't like the loud “clink” when you set that mug down on a hard surface? Do you want to reduce how much your mug slips around? This print stabilizes your tall, narrow travel mug but also acts like an attached coaster, both protecting your mug and helping it slip less, when printed in a soft TPU.

Ninjaflex works great. Harder TPU might work as well but be sure to follow the directions below. Rigid filaments will likely not give you all the same benefits of a flexible, but it may help stabilize your mug.

CUSTOMIZ THAT PRINT

While the included STL is designed for a 22 oz Ozark Trail insulated tumbler, you can easily customize it to fit most tapered insulated mugs. All you need is FreeCAD and the included CAD file.

1. Open the CAD file in FreeCAD
2. Open the spreadsheet in the Combo View by double-clicking on it:
   
3. Measure the diameter (in mm) of your mug at its base.
   1. Use calipers if at all possible.
   2. Record this on the spreadsheet in cell B1
      
4. At a specific height of the mug (either at the top if the mug has a constant taper, or where the taper changes angles) measure the diameter of the mug in mm
   1. Use calipers if at all possible
   2. Record this on the spreadsheet in cell B2
      
5. Measure the height (in mm) of the mug at the point where you measured the diameter in the previous step. Record this on the spreadsheet in cell B3
   
6. The slope of the mug (cell B4) is automatically calculated - you don't need to change that!
7. The height of the stabilizer is set at 30mm. If you wish it to be taller or shorter, you may change that in cell B5
   
8. You may need to change the base diameter to be larger or smaller. It should be larger than the mug's lower diameter by a decent amount if you want it to be more stable! This can be specified (in mm) in cell B6
   
9. By default, the model reduces the radii of the mug by 0.2mm - this can be changed based on your printer and filament. I used a soft filament like Ninjaflex that stretches a decent amount; a harder TPU or a different printer may require you reduce this number.
10. Once you have made all your adjustments, select the model in the Combo View:
    
11. Now, select “Export” under the “File” menu
    
12. Choose a file name and a location that you will remember. You can choose STL as the file format.
13. Open the STL in your slicer of choice, slice and print!
