ZYPOLA 100x100mm ABS Enclosure - EasyEDA Board Outline

I recently came across some decent enclosures on Temu, the ZYPOLA 100x100mm ABS enclosure. These are IP-65 rated, with grommets in 25mm holes in five locations. They are a nice size for many projects, and these were cheap at 4 for about US$7.00.

One trick I have developed over the years is laying out the PCB board outline as a footprint. Draw it once and be done with it for any board to fit in that enclosure. This one is challenging because of the internal radius corners and to leave clearance for the pcb to clear the gromets.

A non-feature of this enclosure is that the four central bosses are higher than the four bosses in the center of each side. There are a few options: mounting the board to the cental bosses and leave the edges flapping loose, cut off the central bosses with snips, add spacers..... None of these particularly appealed to me, so I put holes in the center of the board to let those bosses pass through. The board could easily be changed by shrinking the large holes to 3.2mm to clear a 3mm screw.

The while lines in the board outline are in the document layer and don't show up on the finished board. They are helpful for positioning components when laying out a board.

If you'd like to use this EasyEDA board outline file, search for ZYPOLA 100x100mm ABS under user-contributed footprints. Send me a note if you'd like it and can't find it, and I'll send you the file.

Like many things on Chinese sites, this enclosure shows up under different names. Compare the drawings to be sure.

I do something similar with Eagle 7.x. Its 2D drafting capabilities are very limited. I use a real 2D CAD program to draw a complex board outline, then export as DXF. Eagle has a DXF import function, and you can import into virtually any, non-signal layer. Outline is one obvious choice. Be sure to watch your units. The other catch is to line up the import with the grid. That can be done with the command line but is also easily done using the grid command, which takes very little time and is easier to remember for occasional users. Save as package. In the symbol dialog, create some meaningless symbol and use that and the package to make a device. You can use the dimension tool in Eagle to label if you wish.

Here's a similar PCB outline from my library:

Design the PCB board outline as a footprint in your EDA software. By doing so, any PCB you design will fit perfectly into the chosen enclosure.

Ummm. Yeah, that's exactly what I said.

I just use a big drill bit on those standoffs in the centre to remove them.

I don't understand the intent of having the center bosses taller than the side bosses. The side ones might be intended for a DIN rail.

It does look like an electrical junction box, so DIN rail fitting is a possibility.

I don't buy and modify boxes anymore.
I export the PCB outline (3D profile) to a 3D mechanical CAD program, design the enclosure with all necessary cutouts, then have it 3D printed using a material of my choice. I receive a box usually in 3-5 days. Fits the PCB perfectly.
