AlfaRC Cub-AIO 2in FPV Case | Gridfinity 3x3x9 with TPU Padding

This is a protective case for the AlfaRC Cub-AIO 2in FPV. It utilizes TPU to make a soft padding within the case to protect the drone and batteries from damage. The case is a 3x3x9 Gridfinity box that can be found here: Modern Gridfinity Case . 

What you'll need

To get the files for the box, go to Modern Gridfinity Case and use his Onshape link to configure the box to 3x3x9. Once you finish printing the case you can then move on to printing the Gridfinity 3x3x9 bin that the TPU padding will go into. Print the bin in PLA (0.2 mm layer height, 2 walls, 10% infill). Lastly, it's time to print the TPU padding in 95A TPU. Below I have put Instructions on how to print the TPU padding.

Printing the TPU Padding

TPU can behave differently from brand to brand and from color to color. It's because of this that we need to perform an infill test to see what infill percentage gives us the right amount of cushioning.

In the files for this model, you will find a TPU test cube. Take that cube and put it into your slicer.

Once you have it in the slicer, put in these settings.

0.20mm Layer Height

0 Wall/Perimeters

0 Top Shell Layers

2 Bottom Shell Layers 

Gyroid Infill

Then for infill percentage, we are going to start with 15% and work our way down until the desired amount of cushion.

The cube should look like this:

Once you are satisfied with the cushioning of the test cube, go ahead and print the TPU inserts out and that's it! You can now put your drone, batteries and props, all in one protective box.

If you think I should make inserts for a different FPV drone, let me know in the comments and I will do my best to accommodate.

Thank you.
