Raspberry Pi Electronics Enclosure with Arduino Mega or Rambo Mini and 7" HDMI TouchScreen Display

**5/7/2018** I updated the openscad file to have a 1.5mm base under the electronics board. It seemed like a better idea to give more protection to the electronics underneath rather than saving a little plastic. The module I added to the openscad code is Bottom_Flat() for those interested in that. **9/9/2017** I added a vented top option for passive heat release. **DD_2_TopPlate_Vented_Elec_Pi_HDMI7_Rev150.stl** or **DD_4_TopPlate_Vented_Elec_Pi_HDMI7_Rev150.stl* I also updated the solid top plate version to have less plastic in the middle to cut down on print time. **DD_2_TopPlateBlank_Elec_Pi_HDMI7_Rev150.stl** or **DD_4_TopPlateBlank_Elec_Pi_HDMI7_Rev150.stl**. Use the clearance size that works for you. This is a remix of the Combo Electronics case https://www.thingiverse.com/thing:2466915 to house the raspberry Pi & the HDMI 7" touchscreen (https://www.adafruit.com/product/2407) instead of the LCD displays. mikebaier asked if I could do this & he beta tested it. I thought it was a good project to test how well this design worked for customizing. In this process I did change a couple of ways I was doing the faceplate cutouts & reflected those changes back to the previous design. mikebair had one problem with the display sticking out too far & think I fixed that with the setback display supports on the bracket, but that is untested since I do not have this display. Since there are so many parts & options I put all the STL files into 1 file & you will have to split them out with your slicing program. I use the Slic3r Prusa Edition to do this. https://github.com/prusa3d/slic3r/releases I would suggest you 1st print the test print **DD_2_TestSizes_Elec_Pi_HDMI7_Rev148.stl** to see how well the parts fit together. If they are too tight, print the **DD_4_TestSizes_Elec_Pi_HDMI7_Rev148.stl**. You can delete the bracket on your 2nd test print as those connections stay the same. The DD_2 has a clearance of .25mm for the dovetails & the DD_4 files have a clearance of .4mm. Once you are happy that the test parts fit together for you, I would then print the faceplate to make sure that fits & your display fits that & the left bracket. The right bracket should be your next print. If those fit well, the rest should also since the other parts have been tested. I made one file of shim spacers from 1mm to 6mm. Since that is such a small file, I would just print all of those to see which sizes fit best for you. mikebair used the 6mm, but you might also need another set of shims with the setback display supports. Here is his beta test photos of the remix. https://www.thingiverse.com/thing:2498567 There are 2 other optional backs, one for a vesa 100mm hole pattern mount which works with: https://www.thingiverse.com/thing:795786 **DD_2_BackPlateVesa_Elec_Pi_HDMI7_Rev148.stl** //.25mm clearance **DD_4_BackPlateVesa_Elec_Pi_HDMI7_Rev148.stl** //.4mm clearance or a back that works with the Raspi7inch_Case.stl & Raspi7inch_Lid.stl from: https://www.thingiverse.com/thing:1585924 **DD_2_BackPlateRasp7Case_Elec_Pi_HDMI7_Rev148.stl** //.25mm clearance **DD_4_BackPlateRasp7Case_Elec_Pi_HDMI7_Rev148.stl** //.4mm clearance By changing the variables **Pi_X_Spacing** and **Pi_Y_Spacing** you can use whatever mount you want. You can either put the raspberry pi on the inside back or outside using an additional vesa mount: https://www.thingiverse.com/thing:795786 or the **Raspi7inch_Case.stl** & **Raspi7inch_Lid.stl** https://www.thingiverse.com/thing:1585924 Reference Parts used: I took the dimensions for the Display cutouts from: https://www.thingiverse.com/thing:1585924 I used the raspberry Pi model from: https://www.thingiverse.com/thing:412639 The arduino & fan I got from thing 820960 which does not seem to be there anymore. I increased the height of this by 25.5mm & the width by 14.5mm from the original design to accommodate the larger display. The faceplate is the longest part at 194.6mm which should barely fit on an 8" print bed. For further info on this design, refer to https://www.thingiverse.com/thing:2466915
