I was too lazy to go to the hardware store for the M6 and M4 screws and nuts, so I used the "Nut Job" scad (https://www.thingiverse.com/thing:193647) to
...Show more mix up some printable ones. They seem strong enough for me. There was also something in the base's original design that blocked the M4 nut from going down on one side (you can see it in thingiview), so I converted it to a threaded M6 hole to use the same size bolt as the others. Then I needed to make the hole in the mounting bracket 6mm to match, so also fixed the one side that wasn't quite flush.
Update 1/15/2018:
I made some V2 wingnuts that are a little tighter because I did strip one out.
Also wanted to mount my camera horizontally so remixed the back cover.
Update 1/16/2018:
I took down my camera to add a garage door open/close feature and noticed the housing was fairly warm, so I remixed the back cover to have some vents.
Update 1/25/2018:
I did want the two little holes in the front cover so mixed them out.
Update 2/6/2018 (V2):
Remixed the front cover to have "snaps" to hold the NoIR camera in place.
Remixed the back cover to go vertical, offset, and more vents.
Remixed the mount to go horizontal.
Update 2/21/2018 (V3):
Noticed that the cpu temp of the camera in the garage was running in the upper 70s, so created another remix to hold a 30mm fan. Found that running it off the 3.3v keeps it quiet and the cpu is now in the low 40s.
Also found that the "snaps" in V2 for the NoIR camera break pretty easily so changed those to be standoffs that take screws where the heads of the screws catch on the edge of the camera (forgot to take a pic).
Also remixed the back to have standoffs for the 5v relay.
Update 2/23/2018 (V4):
The cpu temp on my other camera was also hitting the upper 70s even though it is "outside" (under the porch) and it has been pretty cool outside.
So I remixed it again to have a fan on top, and also rotated the vents on the end 90 degrees so they print nicer by bridging.
The standoffs for the camera are still pretty easy to break when putting in screws so I started pre-tapping them by just getting the screw started, holding the tip of a soldering iron against the screw head for just a second, then continue screwing them in.
Took pics of each step of assembly this time and how I tap the fan into the 3.3v
The one inside the garage (V3) the fan is on the bottom and and I set it to blow air into the case, whereas the one on the porch (V4) the fan is on top and I set it to suck the air out and it seems to run a few degrees cooler in the upper 30s, so it is possible that sucking is better than blowing.
Update 3/2/2018 (V5):
Remixed the front to be fully enclosed with thicker standoffs for the camera.
Remixed the back to mount the fan and vents on back.
Update 6/27/2018 (V6):
Created version of V5 Front with a 40mm fan hole per request.
