For an upcoming project I was in need for some card edge connector, just to found out that the one supplier for that particular format that I could found has a delivery time of 8 weeks.

So I decided to 3D-print one …and it just worked like a charm!
Those are the days where I really appreciate the potential of 3D printing!

(…now I can backup my roms to SD card, using as arduino mega)

Are the files for this connector somewhere? What did you use for spring-pins?

same questions like Thantik here as well. Would love to hear more details.

Well the pins itself are not really spring ones. Instead I relyd on the flexing capabilities of the plastic. Of course tolerances between real spring pins and flexing PLa are not comparable and I was sceptic in first place.
But I tested all 24 connections multilple times for continuity without any issue. Also I created approx 10 to 15 times rom-dumps and compared them with a reference file: not a single bit was missing/wrong.
I used 0.6 mm tinned copper wire that I usually use for hand wiring pcb’s (not because I consider them as optimal choice, but just for the fact that I alread had them laying around).

Background: I had the crazy idea to turn the wall in the gaming room to a storage device for ROM’s by the use of QR-codes. Some time ago I found out that QR-codes can store up to 4.000+ characters. The goal is, to design and build a universal device that reads out ROMs, generates QR-codes and prints them out. Also a (raspi/web-cam based) QR-reader that reads the rom QR’s, merges them, can be attached to the game-console to emulate the scanned ROMs. And as always, 3D printing has become an indispensable tool for my projects. So while this topic is not 3D-printing centered, it is at least 3D-printing related.

Fantastic! Thank you for sharing!

For a project I am ordering a 44pin converter to compact flash. This is for running another OS on a Thinclient that came with a 32mb flash memory.
