Well, been busy designing at my 3D Workstation- decided to design a few box mods.
Almost the most fun design job in 23 years as a Senior Mechanical Designer - the Jurassic Park II Mobile Command Center was first! Used to be a designer for Fleetwood way, way back. I was lucky enough to be in the right place at the right time.
The first mod
Stainless Steel Faceplate & Buttons shown.
View of the PV "chopped" in half, exposing the inner structures.
Modeled in a single block of Oak for the moment. All USA parts, US designed and manufactured.
I have partnered with a good friend of mine who was an electronics tech in the Coast Guard. His specialty was circuit board and micro-electronics soldering - perfect for this purpose.
The parts used include the Evolv DNA75 chipset with temp control & much more, a Fat Daddy's 510 Woody connector and a Keystone battery sled.
Part of the design includes a handful of 3D Printed parts including the chipset mount/button pusher; the battery sled holder & the Faceplate.
So far, I've created three different Faceplates. A flat, featureless basic Face; a flat version "Ohm" Faceplate (shown above), and a Faceplate with a contoured surface that provides a buildup around the buttons to prevent accidental firing:
The Faceplates (and buttons) will be available in Plastic, Stainless Steel & Brass (shown above). The brass is pricey comparatively speaking. 4x the cost of SS.
This MOD is the first design - a single 18650 DNA75 made as reasonably small as possible:
1-1/4"w x 1-5/8"d x 4-3/8"h. The battery access door is on the edge opposite the Faceplate, slides open and closed, and uses magnets to hold the closed position.
I have an animation of the complete PV coming apart & it shows the door sliding out. For whatever reason, I can't post it - I get an oversized graphic saying something about a capcha, but can't seem to get past it. It's on Flickr here.
An raytraced frame from the animation:
The doors are cut from the block early in the production process, so they will match the grain when in place. Three different versions of the bodies will be produced - single species solid block; multi-layered, multi species laminated blocks (like our vape stands); and stabilized wood/resin blocks similar to:
This is from one of my favorite sellers on FleaBay.
As said, this single 18650 version is the first design. A very similar dual 18650 version with the sliding door on the side is currently on the drawing board. A third, Side by Side style is also in my head and waiting to be designed after the dual battery MOD is designed next.
Also considering looking into 26650 possibilities too. Well, whatever I can finalize designs on and have available for order by August 8th...
I still have to order some 3D printed parts to test out sizing and looks before we can build the initial test units. Need to test machining methods and work out proper order of operations, etc...
The protos will actually be two DNA40's from dis-assembled new PV's (bought for this) and one with a new DNA75 chipset. Probably one in Oak or Padauk with a plastic faceplate, multi lamination version, and I have a pretty cool purple, blue, slate and orange piece of stabilized maple burl I will probably utilize for one of them.
Pricing has not been determined yet, but should start out under $200, possibly less - for a DNA75 MOD that is 100% US made, parts and labor
I've even been playing around modeling some custom fire buttons, too...
More updates as they happen-
