Someone requested for a part here
So while I was making the part, I decided to record down what I did.
Download these (if you have not done so)
- The Schematic Extension for Inkscape
First download this image
and upload it into Inkscape
Next, download this SVG of connectors
Line it on the image
and rescale the image (SVG image below with PNG at the back. As the forum cannot properly render, please download this file and remove the .fzp extension)
Then, design the part graphic, but first ungroup “Layer1”
This is the most tedious part. and once you’re done you are actually 3/4 done. This tedious process can take up to 2h+, so good luck 
You will get this SVG (I let copy paste do the work)
But, that’s not all.
All these elements have to be moved above the connectors (in XML Editor)
The connectors have to be ordered this way
The easiest way to reorder and rename the pins is to run through E2fRemoveUnusedConnectors.py
So first rename the first pin to connector0pin+
Then, edit → Select All → Ctrl/Cmd + G to group everything
Go to File → Document Properties → Resize Page
Then change all units to in and change scale to 0.001
With width and height locked, change the width to its original
Close the document properties window. Next, ungroup and regroup to remove the transforms, then rename group to breadboard
Now save the svg
and run it with E2fRemoveUnusedConnectors.py
Warning
The python scripts can be fairly rough. They may need to be modified to do what you want

Open the SVG with Inkscape and check if everything went well
At times, the text goes wrong when the program removes PX from font sizes. Then, (sadly), we have to convert everything into paths
Now that we are done, we can move on to Schematic
For the schematic, we want to group the connectors like this
So open a new SVG, then
Press Apply, and label the connectors. You will then get this SVG (right-sclick → save as to download this SVG)
Now, go back to the breadboard file, then ungroup
Delete everything except for the connectors
Group everything → file → document properties → resize page to selection → ungroup
Now, select one connector, and change from
to
Do same for all other connectors and you’ll get something like this
For the path, change from
to
Do second round of viewbox adjustments, then group the path
Group the connectors twice
and rename to
(Note: Case sensitive!)
With that we are done with the PCB view
Go to Fritzing and drag out a generic IC, set its no. of pins to 40
Then, press “Edit Pin Labels”
and set the pin labels
Now, right-click → Edit → Metadata
Change from
to
Go to breadboard → file → load image for view → select file → open
Go to schematic and do the same, but this time, set internal connections (by checking the checkbox
(provided your part which may be another one, has bussed connections)
Go to PCB view, and do the same, but don’t set internal connections
Go to Icon view, then file → reuse breadboard image
File → Save as new part → ok
That’s all! The part’s done.
When closing Fritzing, be sure to save changes made to the MINE BIN
