Brake Pipe Straightener

Simple tool to straighten 3/16" or 4.75mm hard brake lines. Just pass the section of brake line through the pulleys and it will straighten it for you.2 versions included, 12 and 9 roller versions. The 12 roller version I have printed and used, It produces a useable straight pipe. I then designed the 9 roller version with tighter tolerances so should hopefully produce an even better result whilst requiring less filament and hardware. I have not printed the 9 roller version, but expect it to be superior to the 12 roller original. All model files are marked for use with either the 12 or 9 roller version, the pulley file is common to both.12 or 9 each of the following parts are required depending on version chosen;M8x25mm BoltsM8 Nuts
