Refer to the detailed SoW: [login to view URL] We need a product/electronics-mechanical designer to develop a simple passive extension adapter for a removable code/calibration chip used in a handheld diagnostic device. The device currently requires the chip to be inserted directly into a small slot. We want to create a male-to-female extension so that one end remains inserted in the device and the original chip can be inserted at the other end of a short cable. We already have a 3D STEP model/mapping of the chip geometry, which will be shared after project allocation. The project includes: Male insert design Female chip receiver design Short cable connection Simple PCB/contact design 3D-printable housing design Prototype fabrication Testing with the device Complete design-file and knowledge transfer Important: this project does not involve firmware changes, chip cloning, chip emulation, decoding, calibration modification, or opening/modifying the device. It is only a physical extension adapter. The design should be easy to manufacture in India using commonly available PCB vendors, cables, connectors, and 3D printing. Housing should be friendly for in-house FDM 3D printing. Experience with small PCB adapters, contact interfaces, custom connector design, 3D-printable enclosures, and prototype-to-small-batch manufacturing will be preferred.

Hi, I can design and prototype your passive removable code-chip extension adapter with male insert, female receiver, short cable, simple contact PCB, and 3D-printable housing. The best solution is to first review your STEP model, chip geometry, pin/contact mapping, slot clearance, insertion depth, cable length, and mechanical tolerance needs. Then I’ll design the male end that stays inside the device, the female chip holder, the interconnect PCB/contact layout, and an FDM-friendly enclosure that can be fabricated and tested easily in India. I’m comfortable with small PCB adapters, contact-interface design, custom connector concepts, mechanical CAD, STEP-based modeling, 3D-printable housings, cable/connector selection, prototype fabrication, and small-batch manufacturing documentation. Deliverables will include: * Male insert design * Female chip receiver design * Short cable connection plan * Simple PCB/contact design * 3D-printable housing * STEP/STL design files * Prototype fabrication support * Device fit/testing support * BOM and vendor suggestions * Complete design-file handover I’ll focus only on the physical extension adapter, without firmware changes, chip cloning, emulation, decoding, or device modification, and will keep the design simple, manufacturable, and easy to assemble. Best regards Ankit
