norm8332 Posted October 17, 2016 Share Posted October 17, 2016 (edited) Continuing my Atari related 3d printer file releases with a 3d printable SIO plug. If you have access to a 3d printer the file is located here: http://www.thingiverse.com/thing:1831769. Printing the plug requires a very well tuned printer for the best results. I used a highly modified Prusa I3 with a .2mm nozzle and the results were good. I have tested it using contacts pulled from an old AT power supply mother board connector. New contacts are available at Digikey ( http://www.digikey.com/product-detail/en/molex-llc/0008500105/WM2300CT-ND/467825). This is still a work in progress although its fully functional. If you have any suggestions please let me know. Norm Edited October 17, 2016 by norm8332 15 Quote Link to comment Share on other sites More sharing options...
DavidMil Posted October 17, 2016 Share Posted October 17, 2016 This looks really nice! When you say contacts from an old AT power supply are you talking about the 13 metal contact connectors that lock into the female connector? If so, you can buy packages of them from Best Electronics too. Quote Link to comment Share on other sites More sharing options...

norm8332 Posted October 27, 2016 Author Share Posted October 27, 2016 (edited) Just to update..I've been using this with a DIY SIO2ARDUINO SD adapter and its holding up great. Mine was printed in ABS plastic. I have tried it on a 400, 800 and 600XL so far. It was a little tight on the 400 but i think its the plug on the 400 is warped a bit. I recommend printing this with ABS plastic because that's what it was designed with, but It may work well with PLA also, I never tested it. If anyone prints one in PLA let me know of any problems etc. Norm Edited October 27, 2016 by norm8332 2 Quote Link to comment Share on other sites More sharing options...

norm8332 Posted October 27, 2016 Author Share Posted October 27, 2016 prine What printer do you have? I printed it on a modified-for-additional-rigidity PRUSA i3 with a .2mm nozzle, but I also have 2 MendelMax 1.5s that are the workhorses. The 2 MendelMax printers have larger .35mm and .40mm print nozzles. I used the I3 with the .2mm because of the fine details of the plug, but they may print OK on the larger nozzles..I haven't tried it yet. But the next one i will try on the .35mm printer. 1 Quote Link to comment Share on other sites More sharing options...

NISMOPC Posted November 8, 2017 Share Posted November 8, 2017 Would this one fit? http://www.taydaelectronics.com/crimp-terminal-connector-3-96mm.html No. The "wings" would be too wide to fit in each port of plug. Quote Link to comment Share on other sites More sharing options...
ivop Posted November 8, 2017 Share Posted November 8, 2017 Thanks! I was afraid that would be the case. I have a really hard time looking for ones that would fit and which I can buy without $20,= shipping cost... Quote Link to comment Share on other sites More sharing options...
Madi Posted November 8, 2017 Share Posted November 8, 2017 (edited) Would this one fit? http://www.taydaelectronics.com/crimp-terminal-connector-3-96mm.html I wonder if this one will do: https://www.ebay.com/itm/10-x-Crimp-Terminal-Connector-3-96mm-FREE-SHIPPING-/251118500449 It will be great if it fits. I think there is no need to cut the wings !! Edited November 8, 2017 by Madi 1 Quote Link to comment Share on other sites More sharing options...
ivop Posted November 15, 2017 Share Posted November 15, 2017 I just had a couple of them made in Colorfabb XT. They turned out really well, except for the fact that the inner part is too big to properly fit the housing. After a lot of sanding, filing an dremeling I made it to fit, but in the process I discovered the edges (ledges?) inside the housing are not high enough and spaced too close and the "height" of the edges is reversed compared to the Molex plug I used for comparison. That means that once you pull the plug out of a socket, the inner part gets loose and slips out of the housing. Maybe it all fits snugly when modeled, but I guess there is no margin for the fact that parts are slightly bigger most of the time, unless you have a very very accurate 3D printer. 1 Quote Link to comment Share on other sites More sharing options...
ivop Posted March 26, 2018 Share Posted March 26, 2018 Update: I was now able to print it successfully myself at 0.2mm layer height, 0.4mm nozzle, 25% infill, PLA @ 200°C, heated bed @ 40°C glass with 3DLAC, but (important!) with the top and bottom scaled to 101%. Now it all fits perfectly and without any stress on the outer shell of the top and bottom parts! 3 Quote Link to comment Share on other sites More sharing options...

Now it all fits perfectly and without any stress on the outer shell of the top and bottom parts! Yes it does require a highly calibrated printer. Most have printed it as is and had no issues, others may have had to make minor adjustments based on their particular printer type, calibration, and material used. It was designed for use with ABS. ABS shrinks slightly and the shrinkage may also vary from brand to brand. Edited May 26, 2018 by norm8332 Quote Link to comment Share on other sites More sharing options...
