This model is used to allow my favorite and highly recommended featherboard system (https://bow-products.com/) to be used on an Incra fence. The factory plates don't have enough travel to leave room for normal thickness boards. They now make dedicated featherboards suited to this purpose with better clearance and I highly recommend using those instead of this.
These are safety devices, nothing about printing your own frame is safe, do so at your own risk. I strongly recommend CF-PLA for strength and rigidity, 5-6 walls and more than 50% infill.
Please buy the full kits from the manufacturer, the factory parts are much better suited for most other tasks and provides much needed safety to router tables and table saws.
