Flat Kerb/Curb Inserts for Scalextric 1/32 track borders

thingiverse

Did you miss out on the classic black borders for your Scalextric Classic or Sport track that features flat kerbs? Were you unable to procure enough of them for your layout, or did you need the R1 outer as a flat kerb, which Scalextric never produced? If you still have bump kerbs with red and white stripes and are tired of your performance cars getting upset by the transition over that bump, then worry no more! Just print these up and put them in place of the bump curbs. I've updated all the models to include the same type of tabs as OEM border kerb inserts. However, depending on the printing method, the "vertical" tabs can be very fragile and easily snap off during installation. The best way to install the kerbs is to first insert those vertical tabs and then carefully bend the border while holding the kerb firmly in place so that the horizontal tabs can pop into place. If the tabs break, just keep proceeding with the installation, and they may still hold in place fairly well. If the tabs break and the borders continue to come out of the slot, you'll need to glue them in place. Hot glue works perfectly. I have printed and test fitted all these pieces, and they fit well. They've also been serving long term on a couple other tracks in my clubs. My personal preference when printing these is to print them top down (as provided) on a textured build plate to give the top of the border a nice texture. Any type of filament will do. There's no need to spend extra on "strong" filament. Print them with whatever you like best. Update 3/9/2020: I changed the text on each model from my name to my initials plus piece ID, e.g. "R2O" is an insert for an R2 outside border. Update 4/3/2020: I added parts for Right and Left pit lane borders. There are single parts for R and L if your plate is large enough, as well as two parts for each side. Keep an eye on this thing because I'm planning to update the two-part pit lane insert, as well as the lead in/out inserts. https://youtu.be/AFI_WALb4Oc
