PiSec MKIII - Compact Edition

thingiverse

I'm getting a little tired of changing my designs, to be honest. Printed out the body of MKII, and while everything fit together just fine with the POE adapter, Pi, and camera installed, it was a bit too big for my liking. So here's a compact edition. Went in a different direction on the mount this time around. Features: • SMALLER • Hidden network/power cable (POE) • Looks better to me • Front begging for a logo • Entire body held together with four screws • Heat set inserts used in front case for durability • Full 360° rotation and full 90° tilt. Able to look anywhere in a hemisphere. • Printed out nut, had to file ID to get a good fit onto Clamp1, increased bore size .3mm in STL, tight fit not needed here. Changes: * Thinned the walls of the RearCase to 2mm, they were a bit too thick * Got distracted playing Minecraft while the front printed, don't have pics today. Everything seems to fit ok for now though. * Looks like I had both O-rings wrong. The 65mm is 2mm section, the 20mm is 1mm section.... * I split the screw jig so it can be clamped (Lightly of course) in a vise and squeeze down to hold the screw. * Rotated Clamp2 to what I think is the best orientation for printing. Supports in the ball socket would make it rougher than it should be. Upgrades: • Added 23mm screw jig for clamp screws • Regular 25mm would probably work fine too. • Added Ball_TR file, intended for when you want to use 3mm threaded rod and nuts. This one has raised bosses for nuts, since the pockets on the normal version wouldn't allow them to be tightened. • Added ScrewJig_TR file, used to trim threaded rod if you want to go this way. It should screw in until it bottoms out in the front case then assemble over rods and using Ball_TR it should be just enough protruding to use acorn nuts. Notes: * Printed out Ball and Clamp1. These parts fit together beautifully with each other when pritned with 0.16mm layer height. * Problems I ran into were the ball needed a raft under the supports since the whole thing basically sits on top of a support grid. The grid didn't have the surface area to stick down. The raft stuck to the feet a bit tight, that's my slicer settings though I imagine. * Running a .2mm gap, I'll bump it to .28 or so. After seperation the feet seem a bit too large anyway. * The clamp had 10mm hex pockets installed instead of 5.8mm that I've already determined to be a nice size for my 3mm nuts. I have no idea why I did that or how it got by me. Modified files: • Uploaded corrected Ball and Clamp1 files. Shrunk the nut pockets in the clamp to a more reasonable size. Shrunk the diameter of the feet on the ball mount so they'll fit easier into the rear of the case. • Modified Mounting rings, both versions have been changed to give 0.3mm more clearance around the boss on the bottom of the clamp. Was a little too tight to turn easily when I printed it out. • Modified MountRing-4RoundBox. Holes were too small, I was thinking normal mounting plate screws that are 6-32 but these are screws that go into the box itself, #8 or 4mm, so I made the holes 4.6mm with an 8mm large diameter on countersink. They should match most #8 or 4mm flat head screws well enough.
