specs on a Aixiz module

[618smartguy]

Does anyone know where I can get a threaded pipe like the one on the Aixiz module but longer? After getting my Aixiz module, I noticed that aaa batteries would fit perfectly into the cylinder on the back, if it was longer. I was hoping someone knew where I could get a piece to lengthen the Axiz module so it can fit a drive circuit and batteries.

You could probably ask someone on the forums with a lathe to make you one.
