EDIT: Sorry, completely forgot about the camera parts. I've uploaded the .stl files for both mount styles, along with the connector for the gopro style. They come from these designs:
EDIT: And the bed retaining plate, haha. Sorry, been sick, sleeping a lot, little out of it. Should have all the parts now.
So I really liked this design:
But I needed more out of it. The rods I purchased were 495mm long, and I didn't want to deal with cutting them, so I took this and extended it a bit to fit.
I'm also setting up an Octopi controller with a raspberry pi. So I integrated a camera mount with a slot for the ribbon. There is also a second style of mount in case you end up printing a taller object. I'll be including an extension arm soon which will raise the height of the camera. It hasn't been measured for standard gopro mounts, but I'll get a small adapter arm for one of those as well.
Lastly, I just copied over another belt attachment so that both sides of the bed can be held at the same tension. I've been having issues where the right side of the bed would slide loose a bit and the bed would be able to jiggle. A second belt should prevent this from happening.
So this is pretty easy. You'll need:
-2x 495mm M8 Smooth Rods: http://www.amazon.com/gp/product/B0045DWA9C/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
-4x LM8UU Linear Bearings: http://www.amazon.com/Easy-RepRap-Linear-Bearings-Printer/dp/B00ED150S4/ref=sr_1_1?s=industrial&ie=UTF8&qid=1420200644&sr=1-1&keywords=LM8UU+linear+bearings
-2x 525mm (approx.) GT2 Belts : http://www.amazon.com/gp/product/B00FM5SC2Q/ref=oh_aui_detailpage_o06_s02?ie=UTF8&psc=1 (I just picked this up, comes with 1150mm of belt and 2 pulleys.)
-4x M3x40mm(+) screws, I prefer hex heads, less likely to strip, for bearing mounts
-8x M3x15mm screws
-6x M3x25mm(+) screws, I prefer hex heads, less likely to strip
-10x M3 nuts or lock nuts
(For both of the above, you can double if you plan on printing 4x retaining plates, as there are spots for 4, 2 to hold the bed down, and 2 for decoration. I'll be adding a few different designs in time, but as for now I just want it to be functional)
-Remove current bed assembly
-Screw bearing mounts into existing holes
-Tighten with nuts/lock nuts underneath printer
-Insert bearings, place top mount, screw in using M3x15mm. DO NOT OVER-TIGHTEN, or you will strip the plastic and bearings will not stay in place. I want to integrate nuts into the design at a later date to ensure top piece stays in place
-Take the 525mm (approx.) belts and insert into holders on the rear bed mount. Secure with zip tie.
-Insert rods through bearings and press fit into back mount.
-Attach front mount to rods, press fit. Take the belts and insert to belt mounts, and again secure with zip ties.
-Place bed into mounts and secure with retaining plates.
I'd recommend cutting a hole in the front of the printer and moving the cables to go through there. I had some issues with my old heater, so when I replaced it, I re-positioned it so that the cables pointed towards the front. I still feel I need to make a clip for the cables to help with strain relief, so that will come eventually.
It's a much easier build than it appears on initial inspection. Good luck!
