The following assumes that I can borrow originals of these parts to make accurate models. --- Quote from: Ken Layton on May 02, 2020, 09:59:56 pm ---Atari # 99-10061 (Coinco # 904590-2) Coin Return Bezel Atari # 99-10066 (Coinco # 905484) Coin Return Cover Door Atari # 99-10054 (Coinco # 904588-2) Button Housing, Entry --- End quote --- These three should be easy to model. Anyone with entry-level 3d printing skills should be able to slice and print them. --- Quote from: Ken Layton on May 02, 2020, 09:59:56 pm ---Atari # 99-10057 Button Cover, US 25 cent Atari # 99-10070 Price Plate Label, 25 cent Atari # 99-10062 Pushbutton, Red NOTE: 99-10057, 99-10070, and 99-10062 assembled as Coinco # 404734 pushbutton assembly --- End quote --- Anyone will be able to inkjet or laser print the Price Plate Label on Avery clear adhesive labels. - It's the easiest part on this whole list. - I'll include a print-ready PDF and the editable source file so it's easy to make custom inserts like the ones here on KLOV. The Pushbutton should print OK in the correct orientation with translucent red (or other color) filament. The Button Cover is the hardest part on this list to choose the right material. - May need a professionally printed and finished resin print to produce a usable optically-clear part using the original design. :banghead: - I'll probably redesign it slightly to make it easier to produce a usable part. - Worst case, someone else might need to make a mold for these covers and cast them in acrylic. --- Quote from: Ken Layton on May 02, 2020, 09:59:56 pm ---Atari # 99-10052 (Coinco # 904583) Coin Return Lever (a.k.a. "porkchop" ). This operates the coin return linkages on coin acceptors. --- End quote --- This one looks like a challenge. - It will probably take testing a large number of iterations to make a usable, reliable model. - Mechanical forces on this part will require printing it in a specific orientation to increase part strength. - No promises, but I'm willing to try after finishing the other parts. --- Quote from: Ken Layton on May 02, 2020, 09:59:56 pm ---Maybe the above parts could be printed in several different colors? --- End quote --- People will be able to print any of these models in any color they want. :cheers: For anyone that doesn't have access to a 3d printer, there are print-houses like Shapeways that can print the models for you, or this is the perfect excuse to get your own plastic poopin' robot. :lol Scott |

The Coin Return Lever (porkchop) is made of Noryl plastic because of the tensioned flexing it has to perform in operating the coin return on the coin mechs. This part is frequently broken or missing. The original version was riveted to the door sub-frame, but the later versions were slotted to be easy to install/remove without any tools. The later version superceeded the original version. |

Thanks for the additional info. ;D - Definitely confirms that the porkchop will be the most difficult part on your list to repro. Unfortunately, this is all academic until I can take actual measurements off actual parts and plug them into an OpenSCAD Constructive Solid Geometry (CSG) model that applies math functions like union (U), intersection (∩), and difference (-) to basic geometric shapes to make the desired part.

There's an Atari coin door parts page on Thingverse, but the return bezel and flap are not a match for the parts listed above. I have a new 3D printer I haven't even taken out of the box yet, so I guess I'm below the "entry level 3d printing skills" threshold at the moment... |

Haven't looked lately so no idea if anyone else has modeled them. :dunno Scott |
