i have not had any luck  finding a nano peb 3d printable case  that is "shared"  out on the web 

 

so since i have a new 3d printer thought i would try my hand at it for my first foray into 3d modeling

well i actually  did a bit of it (3d modeling) back when halo 2 was new doing halo mods , but most of that was just editing existing  models

 

 

here is my initial test design

will print this tonight (8 hour print time) to make sure the  bottom layer is thick enough and that everything fits tight

 

then i will tweak the openings to look better/ and be more correct to size and position  , and then work on a lid

i didn't have my dial caliper here at my house   so i was stuck using a ruler  and converting inches to mm (pain in the butt lol)

so hopefully it will fit

OK started the print then paused   

the opening for the  expansion connector was to small 

so small edit  and trying again

sweet woke up today with it fully printed wooo

 

and its actually a  perfect fit 

so did some tweaks  (hopefully the power  jack hole is sized right  and in the right spot (still have my micrometer at my shop not at home )

and will print this version while im at work today

so hopefully i come home to a  good print with everything still fitting right

i did increase the left wall thickness to match the other 3 walls  4

Can you show some pix of the bottom side please?

Also, are you building an enclosure here, or is that one side going to be exposed?

Sorry if Im missing something obvious. :)

Nice work!!!

the plan is for it to be fully enclosed
(like the current cases being sold )

For now ,until i find a better 3d design program (one im using now is pretty basic  and take more work than it should to do certain things )

i will probably leave the lid with an opening to remove the cf card

and access the power switch

 

i know several people sell a case 

but after searching the web i  can only find files  for the  cart shell (and fr99)  seems no one has shared the  nano peb case files

so thought i would make something  so cheapskates like myself can run to their local library or shop class and print their own

 

in not promising anything fancy  but it will at least be a layer of protection for your nanopeb

 

if anyone has any design change tips let me know  

for me i just needed something better than the cardboard ive been using to prevent shorting out on the speech synth

slow morning at the store today

so built the lid 

before I left for work today  I test fitted the  peb on my speech synth and fond that due to some of the  component legs  on the solder side of the peb

I'm going to have to add a couple shims  in the underneath side so that the peb's pcb  wont flex when installed into the computer

no problem I'm going to put it up on  https://www.thingiverse.com/ for anyone to do with as they please

I would not say I have the know-how lol   only just got my printer 3-4 days ago

and yesterday was the first time I used the tinkercad software

just a bit of internet searching and some trial and error  is all it took lol

 

I did make some stuff like 15 years ago  for halo 2 but way different software and it was more just importing models over existing ones and then blending them , or   slightly modifying existing models

I've had a lot luck using sketchup. You can add an stl export add-on that makes the process pretty painless. If you decide to go this route I can give you a lot of pointers.

thanks ill  check it out (tried real quick but it does not support IE and that's what I use on this pc)

 

well  got the lid and revision 2  case fully printed

everything seems to be good   

 

for rev 3 (and hopefully the final one )

had to move the power jack hole a bit more to get it centered

make the  opening for the serial port  larger

 

the lid is perfect  except having to move one mounting hole because I'm having to make the serial connector  opening larger

Looks awesome, great job!  I was going to design one for my nanoPEB but glad you've already got an excellent start to it.  If you need another tester, I have a FlashForge Creator Pro and a nanoPEB here, I'd be happy to run a test print here if you want/need.

if you want to try out this  revision (should be about perfect)

and let me know if it fits your peb 

any help would be great

 

ive been printing them at 8 fill  for faster printing  and  even at that low fill the screws stuck and they feel pretty sturdy

 

im printing a  lid now (hopefully last one lol) at 25 fill  to see if it makes a difference

i might to my final case  at 100 fill just so im certain that the screws are going to have something to hold on to

Awesome, thank you!  I just sliced it and it's printing now.  Hopefully, in about 5 hours it will be done.  I used 25% infill using ABS.

ugg lol  I need a faster bigger printer  mine is taking  6 hours just for the lid at 25%  pla lol

it was only 140$ at microcenter open box and other than being small and slow it seems to do ok for a cheap machine

http://www.microcent...Mini_3D_Printer

I was a bit ticked   since they website says 5.9x5.9 inch print size and its not  its actually 5.1 inches

 

thanks let me know if it fits 

the one I just printed  was great  but it blocked the serial screw holes  so the one I posted for you I  widened  that opening a bit more

and the  power  plug hole was  off center to the left  a bit so I adjusted it also

 

 

made this little doodad  to  help with removing the  cf card lol

so

as long as jonecool reports back that it fits on his  nano

I'm calling the above revision final

lol

 

printed the  final  lid last night and  installed it  and everything looks good 

 

here she is

the lower case I'm using  is before an edit I made to uncover the serial ports mounting holes  , and center the power jack better  

but I'm not using the serial port anyway 

 

 

EDIT

 

I may have to make the bottom of the shell thinner

it fits great  direct on my  ti99  but  when installing on the  speech synth  it takes a bit of  work to get it to  install 

 

on my speech synth  the  connector door cover has a lip that   sticks out a bit causing the nano to sit at an angle

 

so I have several options

 

1

try and make a slot in the case that that  little lip on the door will rest in

 

2

make the  bottom of the case thinner  (don't like this idea its already pretty thin )

 

3

take apart my speech synth ad ditch its door  lol

 

I like 3 the best lol

Fantastic!.... Spent the day printing it and it's just perfect.  You know I also have the nanoPEB version 2 and if the power supply hole was moved a half inch or so then it would work for it too.

great did the last revision uncover the  serial mounting holes   and is the power jack pretty centered

 

wich way would the  power jack hole need to be moved to accommodate the ver 2

The serial mounting holes are still tight ( a dremel tool can resolve that)  and the power supply jack is perfectly centered.  The version 2 power jack is about 1/2 inch closer to the serial port.

On the nanoPEB version 2, the serial port lines up perfectly with version 1.  On version 2, from the right edge of the serial connector to the center pole of the power supply is 15mm.

ok thanks 

 

 so instead of doing 2 different cases

how about a universal case for both

 

if you want to try this one for your version 2

i  increased the opening for the serial connector some more (hopefully that's enough )

and just made a large square opening for the power jack that should cover both versions

 

 

 

oh also added a link to the little thumb grip i made

makes it  easier to  insert / remove the cf card

i used some double sticky tape that's used for automotive emblems i had , to attach it   (its not going anywhere lol)

Sorry for not posting back, I had my splicer settings set wrong, I had a bit of a mess as a result -unrelated to your models :)  Re-printing with your latest .stl's tonight.
