This is a ( crude) replacement for part A5 of a Tamiya Thundershot. A5 joins the front gearbox to the bumper and supports the lower arms of the front suspension. It's prone to cracking especially if the bolts have been done up too tight. This one was printed at 5% density and is yet to break. This print might not last long and is only a temporary measure while waiting for an aluminium replacement. OpenSCAD source is included if you wish to edit the tolerances and re-generate the STL.
