Caster Plate Alignment tool. Helps do the basic steps needed to get your car near expected caster. Large print, you'll need a large print bed (300x300) or scale the print down. I used this after installing front end parts like control arms to get a general alignment before visiting an alignment shop. You'll also need a caster level and with anything automotive, this is not intended to replace a professional shop or technician. Adjusting your alignment can dramatically change the stability of your car and should only be attempted by a professional. Printed in PLA with 20% infill was enough to hold up under a 1900lb car.
