Key Fob - AlfaRomeo

Key Fob - AlfaRomeo: I'm the proud owner of an Alfa 916, and it's been an absolute blast to own. This Italian beauty has surprised me with its reliability, considering its reputation for being finicky. I find it quite amusing that Italians invented electricity, but they still can't seem to master it. My key fob, however, was in dire need of a makeover. It had become tattered and unreliable due to its worn-out condition. With my 3D printer at hand, I thought, "Why not give it a revamp and maybe even improve upon the original?" This is the result. Here's how I did it: First, print the parts. Next, carefully extract the guts of your fob from the old shell. Replace the battery with a new one. Insert the electronics into the freshly printed shell. Make sure everything is aligned perfectly and apply some glue. And that's it! The pros are clear: A brand-new key fob A stylish key fob A better key fob, to boot! The button is cleverly recessed to prevent accidental activation. The shape and size of the design have been optimized to improve the range, and I'm pleased to report that it actually works! The logo is a separate part, so feel free to use this design for other manufacturers. As for cons: It's a bit on the larger side, but that's unavoidable given the electronics' shape. You'll need to glue everything together. I strongly recommend using hot glue because: a) It creates a neat seal at the joins. b) Hot glue breaks down in the presence of Isopropyl Alcohol, making it easy to disassemble when you need to change the battery. Bonus: All parts (except alfa_fob_logo_ground.stl and alfa_fob_logo_flipped.stl) should be printed as-is. I suggest using support for alfa_fob_base.stl. You can try a cool trick instead of printing all standard parts in black and the logo in red filament: see if you can get a cool black and red effect for the logo. Instead of printing alfa_fob_logo.stl, print alfa_fob_logo_ground.stl in black filament without removing it from the printer. Remove any brim from that print if you included it. Change your black filament to red and print alfa_fob_logo_flipped.stl directly on top of the previous print, ensuring all support is switched off. With luck, you'll end up with a logo that looks similar to the example image above. Excellent! As a tip, you may need to sand the logo if the edges are a bit fuzzy. Depending on your print's layer height, you might need to edit alfa_fob_logo_ground.stl to make it thinner. :-D Note: 1) Be sure the guts of your key fob will fit this design - it works with the OEM fob my GTV came with. I've included the .123dx file so you can alter it if needed. 2) I replaced the rubber thingy with a proper button a while back, and this design takes that into account. You'll need to get a proper button as well.
