I needed a ryobi battery holder for my tool wall that I am building with the Honeycomb Wall Storage system. I couldn't find one that was super simple to print and the one I originally found and remixed, did not fit the battery well. So I designed my own in tinkercad.

There is 2 sizes, one for 4ah battery and one for the 2 ah battery

This will print with no supports and you will need to also need to print the insert-with-M3.stl from https://www.printables.com/model/152592-honeycomb-storage-wall/files

I printed this with PLA+ and BambuLabs x1 carbon using the strength settings. I let it print the first couple layers at normal speed and then I changed to ludacris speed with no issues.

You will will need 2 m3 x 10mm screws and 2 m3 bolt for this. I am thinking of remixing it so it can print with no hardware needed, but I wanted an easy print with no supports. You might need to change the orientation of the model.
