Prusa i3 MK2 LED Lighting Mount

###Stop! There's an updated version - print that instead :)\r\nhttps://www.thingiverse.com/thing:2667553\r\n\r\n###Update:\r\nI uploaded this before finishing installation. Looking back, I might have handled things differently with this. The tabs at the top of each arm are intended for wire management but don't really serve that purpose well. I may have created a path inside the model for this if I had given it more thought. Other wire management isn't great either - currently, I'm using black tape on the back of the frame for most of it, but I'm looking for a better option.\r\n\r\nThe strip lighting is also not ideal for this. I would recommend using a small LED panel instead. I managed to fit 10 3-light segments on each side (which only draws about 300ma of power by the way, for both sides combined). However, soldering all the connections was a real challenge (maybe someone more skilled with a soldering iron wouldn't see it as such). Additionally, there isn't much room for the wires so you can kind of see them.\r\n\r\nThat said, I'm keeping mine set up this way. It does provide a nice amount of light and I'm happy with my installation. But if anyone wants to remix this into something a bit more polished, that would be great.\r\n\r\nI've included the Fusion 360 file for the left arm and the switch holder, and the right arm was flipped using Tinkercad.\r\n\r\nIn any case, I hope this is helpful to some people.\r\n\r\n\r\n## Parts Needed\r\nLED Strip - Here's what I used:\r\nhttps://amazon.com/gp/product/B00HSF65MC/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1&sa-no-redirect=1\r\n\r\nSwitch - Here's one like I used:\r\nhttps://amazon.com/AutoEC-Rocker-Toggle-Switch-Control/dp/B012IJ38S6/ref=sr_1_13?ie=UTF8&qid=1499352050&sr=8-13&keywords=12v+switch+red+led\r\n\r\n## Notes, etc...\r\n\r\nI was using a LED holder (thing 2120195) but I recently added a cable chain to my MK2S and mostly from thing 2224025, and the light bar wasn't working right. So I decided to look for a replacement. I couldn't find anything that quite matched what I wanted, so I designed this.\r\n\r\nI designed the left one in Fusion 360 and used Tinkercad to flip it for the right one.\r\n\r\nI've noticed the left side does interfere - very slightly - with Z calibration. I'm not sure I could redesign it to prevent that - it seems to just touch the bearing on X carriage. In my case, I'm still able to complete the calibration but sometimes it pushes the LED bracket up slightly. I probably won't change anything for this at this point.\r\n\r\nI've designed the switch mount to fit loosely above the power supply (i.e., it will move up and down) but it may take a bit of pressure (it did with my PETG parts) to get it to mount on the frame. If it's too loose for your liking, being able to move it up or down, you can do as I did, which is to take a small zip tie and cut off about 20 mm or so off the end. You can slip this between the frame and the side of the switch bracket to act as a shim (see image). You could skip the switch - but for me, the switch was nice because there are times I want to be printing but not have the lights on.
