This is a prototype Guide Rail Square Adapter I created for my Ryobi Track Saw. However, I haven't had the chance to conduct thorough testing, aside from doing a basic fit test. Since I couldn't find any files with exact measurements for the rail slots, I decided to upload it just in case anyone wants to create their own. You can easily split the objects and use the section that fits into the guide rail slots for your specific needs.

The fit is very tight, so you may need to make slight adjustments to facilitate easier removal from the rail when not needed. Nevertheless, it's better than nothing. I recommend reducing the Y-axis to about 10mm and conducting a test print of just the section that fits inside the rails beforehand. This will give you an idea of how well it fits into your rail, allowing you to adjust the scale slightly as needed based on your printer's tolerances. any material should work although i would recommend petg and having at least 25% infill gyroid. if there are any improvements i can make to the design feel free to mention them
