I have been pursuing the idea of prototyping some Lynx cartridges, and wanted to see if I could get something that looked similar to an original production cart. Using a set of calipers, I duplicated the cart shell in Blender and I have it up for sale for devs, on Shapeways, who may want to create more attractive prototypes. I have already done some prints myself, working out my own mistakes and adjustments required by the 3D printer. I included the details from the store page below and there are pictures available on the store page. I am selling these at production costs to keep it as accessible as possible (no extra moneys for me ) . Let me know if you have any questions or suggestions.
Also, a quick question to those who are more similar with piracy on the Atari Lynx. Would it be wise to keep this listing publicly available or not? Last thing I want to see is this model being used to make pirated games look better physically. If there is interest from developers, and listing it publicly isn't a good choice due to piracy concerns, I can make it unlisted, and then give access to the print upon request. Regardless, if I ever catch wind of someone selling other people's software with this cart shell, I will take it down.
About this Product
Reproduction of the Atari Lynx Official Cartridge with small adjustments to accommodate 3D printing requirements, and the use of a different model of integrated circuit. Details Below:
*Accommodating 3D printing requirements*
This version of the cartridge has and extra 0.2mm added to both the left and right side of the cartridge. This was to meet the minimum requirement for "Wall Thickness" to ensure that the print would not be vulnerable to breaking. This has been tested with a working circuit board (California Games). It fits perfectly into the console, and plays the game normally.
*Accommodating New integrated Circuit model*
The depression beneath were the circuit board sits has been dropped an additional 0.6mm to accommodate the additional height of the SST39SF0(10/20/40) TSOP package (8mm x 14mm & 1.20mm high). (Data sheet: HERE) NOTE: This has not yet been tested with the actual integrated circuit.
-Plastic isn't quite as dense as and original Lynx Cartridge, but is still quite tough.
-I have inserted, removed, and reinserted ~500 times to test wear on the plastic. Seems resilient and only polishes the the surface where there is pressure and friction when inserting.
-The black hard plastic is currently not available as a polished material. As a result the surface shows scratches very easily. The material is still resilient, but just doesn't look as nice as the other colors.
-Plastic is not brittle, so, even though the 3D printed cartridge bends and flexes more than an original Lynx cartridge, it is still resilient.
-The original production circuit board for "California Games" fits perfectly. When attached to the cartridge with masking tape, and then inserted into a Lynx console, the game plays normally.
-Currently there is no circuit board design that includes the new integrated circuit indicated above.
-Thin/small wall edges are not as sharp as the original cartridge, but still usable and will hold the circuit board and label effectively.
