1986 Nissan Hardbody (D21) Speedometer Needle

thingiverse

UPDATE: I used "speedometer needle 3" in my own truck and after a few weeks it has started to sag a bit. I'm not sure if that's due to the mystery filament I used since I just used the unlabeled stuff that came with my printer since I wanted it to be white, or if it was just way too thin. So, I made a revision, "speedometer needle robust V7". This revised version has almost double the thickness of the original, granted, I have not tested it long-term so I can't say for certain whether or not that will solve the drooping problem. The downside of "V7" is it doesn't retain the same OEM profile as "needle 3". However, the change that is made should not be noticed once it's installed in the vehicle.Almost identical in terms of length and width to OEM spec. The biggest difference is that "needle 3" is much thinner than "V7". "V7" also has a slightly wider diameter hole that will seat with less pressure, but still feels secure. The idea is to prevent damage to your odometer unit during the process of dialing in the clock spring. If anyone runs into issues with long-term placement of "V7" please let me know so I can refine. I would highly recommend using "V7". If you do end up using "needle 3" just also beware that removing it from the print table intact is a challenge on it's own.If you need any help or have questions with anything don't hesitate to let me know!FYI: When you install it, you're gonna have to slightly twist the post it sits on to give a little tension to the clock spring that controls the speedometer otherwise your speed will be off. You'll likely have to download a speedometer app on your phone and just do some trial runs to get it dialed in right. Just know that's a part of the process, albeit an annoying one since holding that post under tension while trying to put a new needle on is less than ideal.
