Tamiya DF02 Front A-Arms

Front A-Arms for a variety of Tamiya DF02 vehicles.

My first gen Gravel Hound had/has a lot of slop between the U-bar/hinge pin and the A-arm inner chassis pivot. I'm not sure how typical this is of later generation builds, but it appears to be due to an undersized u-bar/inner hinge pin. This has a nominal diameter of 2.9 mm while the typical partially threaded hinge pins used on the outer portions of the car are 3 mm (like every other Tamiya vehicle). The chassis/inner pivots match the part tightly (2.9 mm bore) but the A-arm uses the same size hole on the inside and outside (3-3.1 mm). While this may not seem like much, it translates into a good amount of slop out at the wheel. I'm not sure why it was set up this way as my other Tamiya kits that have a similar set up do not have this kind of slop.

Print the arm as you typically would (supports only touching build plate), ream only the outer hole with a 3 mm drill bit. If you have a 2.9 mm bit, feel free to lightly clean out th
