ON3 Congdon Spark Arrestor

thingiverse

Created as a project for a gentleman in Colorado Springs who was building ON3 scale kits for baldwin 2-8-0's (C-16 and DSP&P prototypes). He contracted me to make these Congdon stacks as his previous source had gone out of business. Unfortunately, he passed away before anything beyond the prototype was shown to him. These are in ON3 scale, however are pretty easily re-scalable for other scales if you wish. the template I was given included a separate piece inside the stack as part of the spark arrestor, the model includes 2 versions, one with the internals as part of the main piece, and one hollow stack. Use whichever style best suits your application. My prints for this in ON3 were performed with an elegoo mars.
