PiSec Cam MKII by stmorgan

Last crawled date: 3 years ago

NOTICE: This model has been superceded by the PiSec MKIII. Printed out the Body, CamMount, PiPlate, and Cradle. All fit together fine with slight filing to account for elephant's foot, but this is as far as I got before it just seemed on the large side for what I wanted. Will leave files up, but be warned the mounts and the trim ring have not been tested.
Edit for Clarification:
► "PiPlate", "CamMount", and "Cradle" are used for all versions.
► "TrimRing" fits all versions, camera can be built without it. Sized to fit a 3mm thick piece of acrylic between itself and "CamMount"
► 2x "PiPlateClip" hold the Raspberry Pi onto "PiPlate".
► The plain "Body" file has no cable hole nor mounting lug.
► The "Body_Cat6" file has a 6.5mm hole for network cable, as well as a mounting lug that fits "Mount" and "Mount B."
► "MountB" will require either "MountB_ArmHigh" or "MountB_ArmLow"
► "Joint" works with "Mount" and "MountB"
► "MountC" requires all parts labeled "MountC" including the body that's specific to this mount, which also includes the 6.5mm network cable hole. "MountC" does not need "Joint."
► "MountD" is a ceiling mount, requires all parts labeled "MountD" Works with "MountC_Body"
► "MountC_Body_Sealed" is the same as "MountC_Body" except it has a hole in the back to accept a watertight gland and a small O-ring groove on the front.
► "TrimRing_Sealed" is the trim ring used with "MountC_Body_Sealed" to make a waterproof version of the camera. 1x 65mm x 2mm, 1x 100mm x 2mm, 4x 5mm x 1mm O-rings needed. (OD x thickness) Remember the 3mm acrylic is important if using this design, too thin or too thick won't allow a seal. 1/8" should also work.
► "CamMount-Fixed" has had the outer diameter reduced to 100mm, and two cutouts made top and bottom so it can be gripped for removal from the outer case. The clip slots have also been deepened by another 0.2mm so the PiPlate connection is more reasonable.
Original:
This one should be a much better design than the previous model. As of yet the body will need a mounting lug added, or holes for an articulating type mount to screw onto the back. Made sure the walls were all 2mm thick this time. The faceplate will most likely need support but it should be easy to remove if printed face down. The body may or may not need support depending on how well your printer does overhangs. It shouldn't need any support inside, just to the buildplate on the chamfer.
This should fit a Pi3 and a Waveshare IR camera. Mine is the Makerfocus model from Amazon, but it appears to be the same camera. There should be room beneath the Pi plate for a small active POE to MicroUSB adapter.
Changes/Additions:
3-08: Added a trim ring to pretty up the front. Should allow a 3mm gap between the cam mounting plate and itself to hold a piece of acrylic. I'll have to make a light dam to slip around the lens to keep out the IR glare but should be no big deal. Alternatively you could just trim 3mm off the front of the case in Tinkercad (Import the body STL) to use without the acrylic.
3-08: Added Body with mounting lug, joint, and mount for 4" round electrical box.
Body will need supports to build plate, mounting plate and joint will probably do best with supports everywhere. Screw holes in the mount should be sized for #6 Sheetmetal screws. The camera body should be sized for M3 or maybe #4-40 machine screws. The "Cat6" body and mount files have 6.5mm holes for network cable to pass through.
3-08: Fixed PiPlate, there was a separation in the plate.
3-08: Printed out the CamMount and the PiPlate. Camera fits fine, PiPlate snaps on as intended, though it's pretty snug. Shouldn't have to worry about it coming off.
3-09: Added "MountB" files. (The yellow one in the pics.) I like this one better, it's a two piece mount, the arm can be printed laying flat on the build plate, will be much stronger than the original mount due to the print grain running along it instead of across it. And it looks better. Should just clip together and a 3mm screw can be inserted to lock it in place.
3-09: Fixed MountB ArmLow, mistakenly thought the plate was 4mm thick where the clips slid on, it's only 3mm, adjusted clips accordingly. Added MountB ArmHigh, is the red arm in pic.
3-09: Added cradle to hold POE adapter.
3-09: Printed out cradle. Fits fine with 4x 3mm screws and nuts. Two zip ties secures it fine. I printed with supports on all overhangs over 45*, had to shimmy a putty knife in between support and flat section, pop it a bit on the rounded part of the joint to get it free. Could get away with less support I'm sure, depending on how well your machine prints overhangs, I didn't want to risk a bad print just to see. Now that I think about it, the cradle would do fine printed vertically with no supports needed, and be stronger around the arch too. Would need a brim though.
3-10: Added "UP ↑" indicator to CamMount, Body_Cat6, and PiPlate to make it a little more obvious these parts don't fit together symmetrically. Found a weird surface anomaly on the MountB STL. Looks like a TinkerCad hiccup from a trim box overhanging. It's been fixed and reupped. Not sure if it would even show up in a print since it was shallow.
3-10: Added MountC (Green arm in pics). My favorite so far. The round mounting arm will require supports, and probably some cleanup to make the finish consistent, but it's a nice looking, versatile mount I think. The mounting arm should accept a 3mmID x 5mmOD hot set insert on each side. The mount itself just accepts 3mm screws directly into the plastic. I don't think hot sets are necessary here as the load is spread across 4 screws and the step helps hold it. This one will require the MountC body as the offsets and construction are different.
3-10: Added MountD ceiling mount. Works with MountC_Body, which is held upside down. I recommend printing the MountD arm laying down, it would probably be best to not have the load trying to pull the arm apart at the layer lines.
3-10: Added MountC Body Sealed and TrimRing Sealed. Needs a watertight gland in the back "PG7 gland" from Amazon with 0.49" threads should fit. 1x 100mm x 2mm O-ring fits around the step in the TrimRing, 1x 65mm x 2mm O-ring should press into the groove around the arpeture, and 4x 5mm x 1mm should fit under the screw heads. Of course these should be made of ASA for UV resistance if outdoors.
3-11: Added CamMount-Fixed. Should ease disassembly of camera.
3-12: Added TrimRing-Fixed, TrimRing_Sealed-Fixed. Shrunk diameter of shoulder to 100.5mm to ease assembly/disassembly.
