About this model

There are a few of these already posted but I did not like the style, assembly, or precision of some previous models. Post processing alignment is not necessary. Use a filament with a low coefficient of thermal expansion such as PLA (I used PETG). This model's STP has been included if you would like to remix this design. ###Requires: - Glue - Print Bed >= 242mm OR Print Bed >= 125mm ###Update 3/4/2021 - Indy500fan requested a smaller design. New additional files are 125mm in length. ###Update 3/27/2021 - ReallyJustJan and SrBocanegra pointed out that the 6in metric design had flawed numbers and the files were updated. - The STL files were optimized to use less space.
