Mion DNA200 C-Frame Box Shell

This is the shell for the Mion DNA200 C-Frame mod.  It is required to complete the Mion DNA200 C-Frame mod.

It comes with the pressure mount screen clamp and rounded fire and adjustment buttons.  These will need to be removed with snips before the build.

The screen clamp (tooless pressure mount) and rounded buttons are also included. If you would prefer flat buttons, those are also available, as are the rounded buttons if you want them in a different color.

The DNA200 board is secured with three of these screws http://www.mcmaster.com/#96817a744/=y745g3 (M1.2mm x 3mm). This enclosure is designed to work specifically with 22mm Varitube 510 http://www.varitube.com/510-Connector--Self-adjusting-Center-Pin--14mm-22mm-285mm-Smooth-Top-22mm_p_141.html (the FDV V4 profile 510 is a tad too long to allow room for the output wires).

The battery door is secured with a tongue/groove orientation along the top and back. The fit is pretty tight as is and the door will not come off in normal operation. There are two screw holes along the back bottom that keep the door locked in place (especially helpful if your wire management isn’t that good), but they aren't necessary for this design. I use them to keep anyone from opening the door.  The appropriate screws are found here http://www.mcmaster.com/#96817a787/=y74cb7zzz and are sized M1.4 x 6mm.

I have successfully printed this so the alignment should be fine, but as is the case with all 3D printing materials, print variance does occur. Some sanding and adjustment may be required.

Keep in mind that this design has 4mm thick walls minimum for external fire and safety to meet UL 94 requirements.  Many less expensive enclosure designs are using 1mm-2mm walls, which are less stable and offer little protection from external fire sources and external puncture in a drop event.  The result is a slightly higher cost, but the box is solid and takes LiPo safety into account. 

This screen clamp goes between the DNA200 board and is designed to have the board rest on it. While the DNA200 is screwed down it will apply pressure to the screen and keep it in the screen cutout on the mod. My suggestion is to place the screen in the mod and then place the clamp in before resting the DNA200 in the mod to screw down.
