Mion DNA200 V2 (with Clamp & Button Group)

This enclosure measures  90mm (h) x 50mm (d) x 46mm (w) at the back/approx. 36mm (w) at the front.  This is designed can be used with batteries up to 82mm x 37mm x 23mm (remember that room for the battery cables needs to be considered as well). I am using the Thunder Power TP1350-3SP+25 1350mAh battery for my test print.  A cheapter alternative would be the Turnigy Nano-Tech N1300.3S.25 1300mAh or Turnigy Nano-Tech N1300.3S.45 1300mAh.

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 center hole for the 510 is 9.5mm and will need to be drilled out to 10mm for the 510 connector.  It was left intentionally small to allow for taping the hole with Varitube's 510 tap to allow for screwing in the 510 connector.

The battery door is secured with a tongue/groove orientation along the top and sides.  There are two screw holes along the back bottom for additional security if desired.  The appropriate screws are found here http://www.mcmaster.com/#96817a787/=y74cb7zzz and are sized M1.4 x 6mm.

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.

A test print of this has been made and minor issues corrected as of July 29, 2015. But as is the case with all 3D printing materials, print variance does occur.  Some sanding and adjustment may be required.  For example, the buttons should sit flush on the interior side...sanding them down may be required.  Also, the botton of the rear door may require a .3mm to .5mm reduction and the rails may also need to be sanded down.  The door and rails are spec'd to fit, but again print variance does come into play.  Please be ready to work in tight spaces and plan out your cable runs before cutting and soldering...orientation is key!
