Attention: Please take a look at the project's update section down below.
With the Raspberry Pi camera holder "The Round Tower" you have a convenient mounting for a Raspberry Pi camera, to observe your printing job or make time lapse videos.
Because a 3D-printer needs a lot of attention!
Using an infrared filtered camera you can watch your prints even in absolute darkness, given that you have some infrared LEDs connected.
For this purpose I use the Kuman camera as shown in all the pictures (affiliate links ahead...).
It comes with two ambient light controlled infrared LEDs. As the LEDs get quite warm, I have heatsinks attached to the back copper plate to cool them down.
The Round Tower's arm uses the hexagonal hole on the side of the Prusa LCD controller's brackets and is secured Prusa-ish with a ziptie. :-) No screws or nuts necessary!
It also has a covered ribbon cable duct that hides the rather ugly ribbon cable which leads it behind the LCD controller. From here it can be guided just like the LCD's ribbon cables all the way to the back of the printer. If you don't have your Raspberry Pi sitting somewhere in the back of the Prusa i3 MK2, having the ribbon cable behind the LCD controller should give you a good starting point for a nice cable routing.
If you want to route the cable all the way to the back, you'll need a longer cable. I used an 1 meter flex cable:
Don't like having your camera placed at the left hand side of the printer? No problem!
The Round Tower has a symmetrical geometry and can also be mounted on the right side.
The camera's bracket does not need any other tools either. Just guid your cables through the rounded slot, connect it to the camera and snap the camera into the bracket. Done!
I have chosen this distance and angle for the camera, because it results in a simple build with a good viewing angle, especially for the critical first layer. But if you don't agree, don't worry. Having the camera bracket sitting on a 8 mm in diameter socket, there will be more extensions in the future to place in between, like adapters for increasing the height and adjusting the viewing angle. And it should be also fairly ease for you to design your own extensions (see dimension drawing). If you do, please share them on Thingiverse!
Please also take a look at my other designs, printer parts and tools.

Sending a tip over Thingiverse will buy me some coffee to stay productive. :-)
Thank you very much.
Original Prusa i3 MK2
0.2 mm on a 0.4 mm nozzle
With the newer versions comes a fantastic new infill pattern: Cubic
I used it for the camera holder and it worked great.
For the arm, you should enable support. The settings for the support I uses incl. a preview screenshot can be found in the projects pictures above.
The wall thickness of the outer shell where the ribbon cable is guided through matches exactly two perimeters, if your perimeter width for a 0.4 mm nozzle is at 0.45 mm. This gives enough strength for the construction and speeds up the print.
