Added f3d per request :)
UPDATE - August 31st, 2019
I have finally iterated enough that I feel this is no longer a work in progress :)
The v3 version of the STLs are the most current version. If you print them outer face down on your build plate you do not need support and they are pretty easy to print.
- I strongly recommend screwing the screws into the holes that are meant to receive them before trying to assemble anything. It helps ALOT!
- I would also do all your wiring before hand. Like leads for buck converters, fan and Pi
- With a bit of convincing the hex key will go through tabs for the bottom to allow for easy tightening of top screws
- Attach fan to Top
- Attach PI to Rear
- Attach SKR 1.3 to Bottom
- With Top laying flat on table, alight Rear, Left. Insert 1 12mm M3 through Left and Rear and secure to Top.
- Align Screen with Left and Top. Insert 1 12mm M3 through Screen and Left and secure to Top
- Flip case on Left side and install buck converters. Plug into Fan and Pi
- Align Right with Top, Rear and Screen. Attach with 12mm M3s
- Tilt assembled case onto Screen and install screen in opening
- With case laying on Top gently flex sides out and install Front. (IMPORTANT: Please see image of how I fed my hex key through the tabs for the bottom in order to easily screw in. BE CAREFUL not to over tighten, it will bump out the front :/ )
- Lay case on Left of Bottom and attach all wires
- Flip to the right over Bottom.
- Test to make sure wires are not hitting you fan and everything works
- What I did for the bottom was rotate my printer so the case hung off my desk and screwed in bottom screws
Optional - I put felt pads on the bottom of my case to make clearance for the screws. I also, sometimes don't screw in the bottom
6 - M3 x 12mm (Corners of walls)
4 - M3 x 15mm (Bottom)
14 - M3 x 4mm (PI, Screen, Mainboard, Buck converters)
2 - M2 x 4mm (Buck converters)
NOTE: These are just what I used, I'm sure you could make due with others
THIS IS A WORK IN PROGRESS
I decided to make an external case for my Ender 3 that contains all my electronics. I made this in Tinkercad and is far from finished. I figured I would make this public to gain feedback :)
I'm in the process of re designing it in Fusion 360 so it is easier to iterate on. I will make sure to update as I redesign but figured since I am using it successfully I would share.
- I needed to get creative with screws to build the case since I didn't measure depth well enough
- Buck converters screws were a little hard to attach so I ended up glueing them in place
- Need 90 degree USBs to attach PI to SKR. I ended up wiring PI to SKR using GPIO jumpers
I printed each part separately and outside face down so the finish was shinny from my glass bed.
I also printed with a brim to avoid warping. Feel free to check out https://www.thingiverse.com/thing:3836250 which is a little tool I designed to remove brims. I was sick of removing them with a razor :)
