(As I was struggling with my printer, and waiting for parts, I decided it would work at some point… so i worked on a housing )
I designed a housing that features a door, and also guides the air to the power supply.
I will share when the design is roughly done. There is a lot to do for me still:
solve some interference
the forth screw base over the PCB was not present in my print, but since the corner comes up a bit, I am putting that in as well.
design the print supports for the door
print the door
correct
upload/share
For now; I finally have the main housing installed:
I am happy with the overall result (and my printer doing this right for 6 hours!)
…As you can see, the back corner comes up a bit, thats where it needs a connection
The lids fits on my housing, but I had to make a lot of adjustments (cutting …grinding etc). The PLA tends to hang a bit at the overhangs, causing things that are supposed to slide to interfere a bit.
–> So… some last work on the file still. Make the clearances a bit larger etc / 4th support / reinforce supports a bit more / improve lid snapper > UPLOAD.
am thinking about integration with the new cover sheet, attachment features to it etc.
(@ Velleman: Would like to know what the preferred safe ventilation hole size would be, if possible… TNX)
Well, I made a few changes, and hope most interferences are solved. Anyway, the zipped files are available for download at my website, for those who are interested :
Great job, thanks. However, unless I am mistaken I think you have uploaded the file for the main housing twice as the picture labelled as the lid housing with support downloads the same file as the main box with support.
Tnx! looking at file correction now… I corrected the upload error, the door with support is there now.
Heat:
I hope not. The idea is that all air from the ventilator is directed over the circuit board now… (thats why the holes are on the opposite sides)
but maybe there are also side effects??
I was planning to find out in the next print, maybe measure it hmm
I can now confirm there is a steady firm cool air flow over the board with the housing, coming out of the oposite side like it should. I have done quite a few prints without any more heat problems now. Also did a second print of the housing. I will upload the steps if anyone like to make alterations.
Ok…The IGES files are also on my site for those who like to change things. If anyone succeeds in printing the housing, and anything needs to be changed please let me know. Tnx
As a tip… use a thin line skirt at 1 mm to check the position of the housing on the bed before printing. Then you will manage to place it exactly right, otherwise you might exceed printing limits (!!)
I am a newbie in 3d printing but i am very satisfied with te K8400 printing results till now. So I decided to try printing your very nice mainboard cover.
Unfortunately I cant print it due to problems with the supports on the edge where the flat cable from display should come in. They are not printed. I opened the iges file in my 3d CAD Program and noticed that there are missing some surfaces. (I am not sure if the program displays iges files error free) For example the wall with the hole pattern seems to be missing completely except of inner areas of the holes and the borders on bottom and top. Also the not printed support structure partly seems to be missing.
Curiously the preview in Repetier seemed to be ok. Can you imagine the cause? Perhaps you can post or mail me your slicer and print settings.
Tnx for the feedback.
For now I cannot fully understand the cause of this. In the meantime i have grown more fond of the standard supports (and understand them better), you could try to download the housing file without supports, and then add them in Repetier.
I prefer to use lines-support only in one direction, app 2-4 mm apart. You can set this in the slices settings (structures).
Make sure to print a skirt first(1 or 2 lines wide, set very close to the object) to see if the housing ends up on the right spot on the bed.
I will also soon check the IGES,/ look into it… , maybe you can download the STL?
