1 Simple Enclosure
The Simple Enclosure is meant to wrap a "skin" around the camera's electronics and CNC milled metal skeleton parts. The Simple Enclosure is designed in a way that can be produced with any consumer 3d printer.
2 Transparent Enclosure
A transparent enclosure is useful for showcasing the camera's printed circuit boards and for allowing to understand quickly what may or may not be going on simply by looking at the camera's status LEDs. The design is made so it can be laser cut with a 3mm thick acrylic glass. Acrylic glass comes is many variations and colors and could also be used to print logos or text labels on the exterior.
Simple transparent enclosure for the AXIOM Beta, version 0.2.
Key : Black => to be cut ; Red => to be engraved ; Green => comments (not to be cut or engraved)
Open and edit the above image with Inkscape or similar.
Note: There may be scope for improvement by making the case slightly bigger (few mm wider for the front and back side), so that the HDMI cable can fit nicely in the enclosure (and you don't need to shave some plastic off the cable). If you make any alterations please update this page with modifications accordingly.
3 AXIOM Beta Compact Enclosure
CNC milled from aluminum.
Onshape 3D CAD: https://cad.onshape.com/documents/d3c8114f3340b3a0f1148960/w/c0701faed5886a1b055b595f/e/354e8363457cbbbdec3ed121
3.1 IR/UV Cut-off Filter
The visible spectrum that humans can see ranges from 380 - 750 nm.
Currently we are shipping Dev Kits with Haida Pro II MC Digital Slim UV / IR 390nm / 750nm filters.
Hoya filters offer a narrower band of 390 nm - 700 nm - will need to be tested how it impacts less red tones.
http://www.optics-online.com/IRC.asp?PN=IRC30-50x50 50x50mm for 39$ for sample (volume pricing likely lower and on request), 1.5mm thickness
UQG Optics offer 40x40x1.1mm UV/IR Cut off filters with 400 - 690nm bandpass
3.2 Thread Inserts
We want to use thread inserts instead of cutting threads into the aluminum ( -> stronger, less production steps, easier to replace thread insert when damaged later):
Ensat from Kerb Konus seems very suitable:
