Update 7/30/17: Version 6.1 Updated design to fit 3rd party shells better, it still works in original shells. Also updated design a bit for even less support material needed.
Update 7/12/17: Version 4.99 and Version 5 uploaded
v4.99 is much more streamlined and fits the edges of the opening much more cleanly.
v5 removes most of the overhangs for a quicker print that uses less support material.
This insert is designed to complete the area surrounding the USB-GDRom. It just pops into the opening on the top shell and sits over the mod.
I have a newer version of this mod that fits the opening better and does not have my username on the side, I sell that version on eBay.
