Within this thing you can safely store your Hubsan X4 with spare parts, usb-card, propeller tool and batteries. The original box was intended for the Hubsan-X4 - H107C On request I added a box for the Hubsan-X4 - 107D (only the 4 little circles inside are 10% bigger, 11mm inside diameter). I alse added the cover with the Hubsan-X4 text inside.This thing can be printed without raft and supports. Any settings for this box are possible. I printed it with 0.3mm layerheight. The USB gap is a little bit small but I inserted a USB adapter for micro-usb which fit tight. You can also put the tool for the props. The cover must be printed last. You can measure the box because with ABS it shrinks a lot. I scaled the cover a bit. How much I don't remember anymore but I printed it 2 times before I fits right.
