My last ATU box is for the ATU-10 as well, but since it is so short, I had to make a new battery box that sits on top behind the radio holder.
The battery box is a bit narrow so that batteries do not fall out.
Please note that the plastic may shrink a little and that the sliding slots may become a little tight on the ATU box, I solved this by lightly sanding with sandpaper and filing down the two small pins that are meant to hold them in place. The one in the pictures is printed with Layer height 0.2 and PLA.
Recommend that you turn on support when printing the radio and battery holder, it has a small hanging edge that needs support.
Note !
ATU-10_Body-Box_w_Slider has been given a rev.1 as after checking a bit at different sales outlets I see that there may be a slight difference in the dimensions that they state on the chassis of the ATU-10. Check the dimensions so you download the right size, if anyone comes across other sizes of the ATU-10, give me a hint and I can adjust with other dimensions.
