Hi all, I purchased an Raspberry 3.5" Touchscreen. I couldn't find a good place to mount it easily so I was going the hard way and desinged myself a nice holder that fits on my Ender 3. Check out my Profile for some more Ender 3 upgrades. :-)

Edit: User howchoo created an very well written text & video guide! Please Check out his make for more details before you start printing: https://www.thingiverse.com/make:707262

NOTE: I added a complete guide on how to set up your raspberry to work with octoprint, touchscreen and camera. Many people have trouble with this and I thought this may be helpful to some people. Scroll down to the very bottom.

This is made to fit for the Raspberry Pi 3 Model B: https://www.amazon.de/gp/product/B01CD5VC92/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 It might fit other Raspberrys as well but I'm not sure.

The touchscreen I used was this one: https://www.amazon.de/gp/product/B01JRUH0CY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Again my case might fit other 3.5" Touchscreens as well but you have to try yourself. :-)

How to assemble: Scroll down ;-)

The Camera-Mount I used (not created myself): https://www.thingiverse.com/thing:2886101 Custom bracket for better clearance to the touchscreen added to my things files: "6_Ender3_Camera_Bracket.stl"

If you want to install a MicroSD to SD Adapter print "0_1_Ender3_Touchscreen_SD_Holder_Base.stl". Remove the plastic housing of the SD Adapter. If it's too loose simply put a piece of tape around it. I used this one: https://www.amazon.de/gp/product/B01C84YKVA/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Changelog:

• Added another backplate for the pi to install a 40mm fan
• Added a smaller clamp to get a little more clearance between frame and clamp
• Removed the camera-cable hole from the pi case and increased the height of the HDMI-hole in order to feed the camera cable trough that. That makes installation much easier.
• Added touchscreen-support (between pi and screen), that way everything is much more stable instead of using foam.
• Added pictures of assembly
• Added complete guide on how to setup your raspberry & touchscreen
• Added my version of ModMikes PiCamera Bracket, that way it's not in the way of the touchscreen. He allowed me to: https://www.thingiverse.com/thing:2886101/comments/#comment-2018042
• Added guide as pastebin link to fix some errors
• Added how to backup your pi image to the guide
• Added "0_1_Ender3_Touchscreen_SD_Holder_Base.stl" if you want to install an MicroSD to SD Adapter.
• Added Info abot howchoo's guide
