Here is my version of a tire truer for carrera 132 cars.

in the raw files there is a version to use with braids. braid slot is 4mm in with and 2mm deep.

u can print more dovetails for more different sandinggrits.

it wil fit most carrera cars

Assembly: you need a old track where u take the rails out and slide them in the slots, take som cable and put them inside the rails end the other end connect it to the race track test if the connection is good, if it is hot glue the cable and the rail in from the back side.

the dove tail need little sanding on the bottem edge so it wil slide in smooth.

use thin dubble side tape to add sandingpaper on the dovetail.
