Enclosure/Bumper for Easy/Newbie PCB

@barduino - Nice work!!
Is it ok if I link to this box from the EasyPcb?

[barduino]

@sundberg84 , absolutely, please do!
Cheers

What is your method of fixing the lid to the base? Or am i missing something as i haven't opened the included files yet?

[barduino]

Hi @Samuel235 ,

It just snaps in. The lid sits on the first lip of the base. It's actually quite tight.

[Samuel235]

@barduino - So its based on the printed having been set up to as such results are produced and that the tolerances allow it to be tightly too then.

[barduino]

Hi @Samuel235 ,

And it works fine, whatever the calibration error is, it's consistent.

The base

The cover

So in reality, the finished part size might not be exactly that, but whatever the difference is, it is propagated to both parts. This probably wouldn't be true if I printed the parts separately in different printers.

Anyway, we're talking about tenths of millimeters.

3D printer generically are very precise.

Cheers

@barduino Awesome project! The links for downloading the files are not functional anymore. Can you repost?

Thanks!

@barduino It doesn't look like there would be much holding it in place. Here is one I did for a wall mounted temp/humidity sensor.

@chorob The links are broken if I click them normally, but if I open the link in a new window or right-click and select "save as" they work. I'll try to figure out why that happens.

This is a forum problem, you need to open links in new window for them to open (Ctrl key works also).

@Nca78 That kind of worked. It downloaded the STL file as a .bin file. Had to manually change the extension from .bin to .stl. It loaded but it is just the base part and does not include the main enclosure. Thanks! Chris

[mhkid]

@barduino - Am I not understanding something because the .stl seems to be just the base and the not the cover. I borrowed a friends 3D printer so I am new to using one, it definitely could be my error on this. :-)

[dbemowsk]

@mhkid What are you planning to use the box for? I have the one that I posted above out on thingiverse. I have the OpenSCAD file so you can customize things if you want, but if you are okay with just a vented enclosure that accepts a 2xAA battery case, then just grab the latest V3 .stl files.

@dbemowsk I saw yours and it looks great. I want to have one without the vents and have it more enclosed. I supposed I could modify yours and not have the vents but like I said I'm new to the 3D printing. What software do you use to create / modify the designs?

[dbemowsk]

@mhkid I just uploaded an .stl file of the cover with no vents. Look on the thingiverse page again for "sensor_wall_box_no_vents_V3.stl"

[dbemowsk]

@mhkid The software is OpenSCAD and can be found at www.openscad.org. I have all of the OpenSCAD files on the thingiverse page. OpenSCAD files look much like a structured programming language, and works in much the same way. I have configuration variables in there to change some of the design fairly easily. If you want to give it a go, I can give you some pointers on how to use the file.

[mhkid]

@dbemowsk I'll go take a look at it, thank you. I also see the version you have that doesn't have vents so I'll try one and see how works for me first.

[dbemowsk]

@mhkid Just a note, There is a relief on one side of the inside of the case. That side is where the nRF24 radio goes.

Unlike barduino's case, mine mounts with screws. I use 2mm x 5mm screws, but I think 2mm x 6mm or 8mm would work better. I worked with what I had on hand though. I would stick with 2mm diameter though.

For people searching the complete stl files of the box and the cover.
I exported them again from the sketchup file.

Hmm, how to upload files here? Only images are allowed by the server?
I've uploaded them to my thingiverse place: https://www.thingiverse.com/thing:4694746

Anyway, I will describe it too

• download the sketchup zip file from the first post
• dezip it and get the skp file
• get an account on the Sketchup online website (free version)
• open the sketchup file
• export to stl via the menu at the left

If you want the two parts apart, delete one of them in the sketchup designer and export the other. Don't save!!!
Do undo and delete the other part. Export now the remaining part.

@evb I've added stl files to the list of allowed file types. Feel free to upload again if you want to.
