Worked quite nicely! Used a Sharpie for the details.

This was my most expensive print, it cost me $700 for new tires.

Had to use the pin from the remix.

Had to do a little rework but it does its job very well.

I like the clean-looking design, but the middle pin was far too tight to fit into the body as shown. I think the tolerance should be increased to at least 0.15mm for the majority of people. I printed with Sunlu Jayo PLA @0.20mm variable layer height while using a 0.4mm nozzle. Thanks for sharing!

Works great! A little bit of sandpaper on the sides and the top of the sliding pin helped it move smoothly. I would recommend a filament change for the markings instead of sloppily hitting it with a sharpie like I did.

Printed in pla, the text ripped of in some parts so I had to use a marker, also the tolerances aren't that great

had to trim the edges of the slider a bit to get it to work but now it fits nicely. thanks for sharing!

Nice model. Thank you! Printed PETG.

Cool practical print. I found I had to lightly file the sides of the needle before assembly otherwise it was too snug of a fit.

“Tire is not legally bald” is not the same as “Tire is OK”.
An “OK” winter tire depth is also not as shallow as an “OK” summer tire, so the !/check scale on this is easy to read but a bit simplistic in its advice. I used a few Sharpie pens to colour-code my scale.

It is much easier to fit into a wheel well than are my calipers, so it suits my current purposes, but I don’t expect it to last a long time.

I suspect the ability to slide the pin may vary with %flow and elephant’s foot, based on other comments. Mine has a slight stiction at one point in the track, but otherwise slides well and is not so loose that it would fallout.
