Ender 3 bed handle with removable Raspberry Pi camera mount

thingiverse

As for the hot bed of my Ender 3 Pro, I suppose it will also work for the standard one.\r\nThe arm has a hole where you can place a support for a Raspberry Pi camera (Rev. 1.3).\r\nThere are two possibilities: a small fixed support and one with an articulated arm.\r\nThe camera box has two variants: one with a clip and one without, but with a hole that the clip can be inserted into by pressure, if it doesn't fit you'll have to scratch a little in the hole. I did this because when printing I wanted the back of the box to be in contact with the bed for a better appearance.\r\nTo attach the arm to the bed, the leveling screws of the same printer are used, to attach the support I have used an M4x10 hexagonal head screw, there is a piece that fits into the screw and makes it easy to tighten by hand. Also, note that there is the possibility of printing the support with and without a hole for a nut, I have it with a nut but I think it will hold perfectly well without one.\r\n\r\nRequired materials:\r\n\r\n-3 M3x10 Allen screws with flat head\r\n-3 M3 nuts (Optional)\r\n-1 M4x10 screw with hexagonal head\r\n-1 M4 nut (Optional)\r\n\r\nPrint position:\r\n\r\n-All parts with supports in all places.\r\n\r\n-The clip faja is to hold the faja (flat cable) and not to pull it, it hooks onto the profile that holds the Z axis pulley from below. It holds the faja against the profile.\r\nTo print it you have to lean on a side with the open part facing up, so it has more resistance.\r\n\r\n-The clip faja 2 also prints leaning on the side, this one attaches to the arm itself, you can put 1 or 2. The clips are not essential but with them the faja looks better.\r\n\r\n-The arms 1 and 2 print leaning on the flat head of the avellanado.\r\n\r\n-The camera box and its lid print it with the outside part in contact with the bed. In the version with the integrated clip, place it with the hole where the camera is housed facing up.\r\n\r\n-The support also prints better leaning on the side of the flat head.\r\n\r\n-The rest of the parts print as they appear in STL.\r\n\r\nVideos:\r\n\r\nhttps://youtu.be/oLqAfgWBBbc\r\nhttps://youtu.be/A_AM9aaF_AE\r\n\r\nUpdate 02/10/2019:\r\n\r\n-I have removed the rounded edges from the arms so that it is easier to print them, I have also made some grooves for the new faja clips.\r\n-Added arms with a hole for an M3 nut, sometimes the screw does not make the thread well in the plastic and does not tighten properly, "it passes the thread", I suppose that with a thread cutting tool it would not happen.\r\n\r\nUpdate 03/10/2019:\r\n\r\n-Added clips to hold the faja from below the Y axis profile until the back of the printer. By placing these clips under the profile, the clip faja becomes obsolete although I leave it for those who prefer it.
