Hi!
The speedo on my GTS today kept fogging up, so to clear it out, I removed the little rubber stopper that you use to set the clock, and yes, as you can guess, I dropped one of the little plastic pins that are attached to the rubber stopper ( there are two)

Anyone know what those pins are called, and where to get a spare one??

Cheers

You may have to get a whole speedometer set.

For just the little plastic pins? If I had a 3D printer, I could print out the pins myself! If I can't find anything suitable, I'll have to resort to using cocktail sticks!!

That is a thought...... although my original problem at the time was that the bloody sppedo was fogging up most of the time, so maybe something like this? https://www.sip-scootershop.com/en/products/speedometerrev+counter+sip+_mv91402bj

Yep. We're all dying to get one of those. But they're so expensive. I don't have European money.

The one thing I really hate about the GTS instrument panel is that if I have polarized goggles on I can't see the digital part of it. It really sucks.

I just got a 3D printer and I'm like a kid with a new toy. Could you send pictures and measurements? I'd give it a try.

I'll certantly give you the size of the thing, let me take a photo of it as well!
If successful, you could make a fortune selling the pins, co's I bet I'm not the only one losing the things!

This is the pin next to the rubber bung that goes over the speedo face

[/url]

And here's the dimentions of the pin!

Hope you can see the dimentions

H 21mm
W 3mm
top of the "hat" say 3.2mm
length of the "hat 2mm

I'm guessing the purpose of the pins is to extend to push the switches?

W 3mm

length of the "hat 2mm

To put those into US decimals:

H .827
W .118
top of the "hat" say .126
length of the "hat" .079


Doesn't look right. only .004 on a side between the flange and the shank.

Recheck your hat diameter.

Will do, but I think the length of the pin is more important that the width of the "hat" as the "hat pushes into the hole in the rubber bung!

Not at the moment. It will be white plastic.

Yes, it looks like the hat diameter is critical if the part must fit in holes in the rubber part. Also, check that the pin will fit though holes in the speedometer face, if there are any.

I questioned the hat diameter because the photo seems to show a bigger difference in hat/shank diameter than .004 on a side.

I see what you meant.

I'm afraid a part that small is not going to come out well on my printer, at least without some fine-tuning. In fact, the first attempt looks obscene. You might be better of with a stirring stick!

I saw one like that in an adult toy store. It might have been bigger, though.

You might have a solution! I wonder how thick they are? If they're too thick, they might not fit in the little holes near the clock! They must be no thicker than 3mm!

To get the fog out, place a packet of desicant beads over the clock button hole and seal over with cling film. A few days and it will draw out the moisture.

Do you have a hobby shop that sells plastic models and model railroad equipment? They will have styrene plastic rods and tubes that you can glue together and make what you need. Take your example with you and compare sizes.

I have a printer in the classroom, if you send me the file in .stl format I can give it a shot too. PM me if you think itís worth a try...

Experimenting...
Printed on its side this time. One side is slightly flattened, and it has a larger diameter "hat" at each end (due to a slip-up in my CAD design) but it's much better. The actual diameter of the end is about 3.25mm. I'm not sure that the diameter is right yet because, as NightWing says, there's too little difference between the end and shank diameters.

That's also quite impressive. Slightly different budget involved, but hey -- you have a pretext now.

Kind of like taking your bike in and getting an Eu5.000,00 oil change where they throw in a new bike for free.

JKJ-FZ6 sent over his design, here is what my printer came up with... The bottom (hat) is a wee bit wider than the rest, it may not look like it on the picture because of the downward perspective.

Let me know if you want it.

Eureka!
Thanks to everyone who helped in this matter, but the old British ingenuity came through!
I used a cotton bud, snipped it to the correct length, and screwed a very small screw to give it it's top hat- an added extra is that if it gets lodged in the small hole where the pin goes in, a magnet will soon get it out!
Take that Piaggio!!

I bet the golf tee would have worked. If it was too wide or too long, just sand it down to proper size.

I guess this DIY essay is also for personal satisfaction.
However we work better with the metric system.

I found it frustrating trying to find such a small part, - I couldn't even find the small bung that covers the clock on the speedo!

I haven't found a place out there that sells such parts for the Vespa GTS!

I suspect Piaggio buys the speedometers from a third party as an assembly, and it's the Smallest Replaceable Unit from Piaggio. If there was a huge demand for these pins some supplier would put them on the market. Otherwise you must make your own.
