Ribbed routing table insert (f360 project attached)

thingiverse

For a Bosch routing table, this insert boasts a 42 mm opening, providing approximately a 6 mm clearance for my trusty 30 mm corner bit. As a CAD exercise, I designed the bottom with ribs for added strength, mimicking the OEM insert's (the red one in the picture) design. My creation turned out slightly stiffer than its counterpart, but the ribs proved effective, ensuring it drops right into place without any wiggle whatsoever. I've attached the Fusion 360 project, which is fully parameterized - simply navigate to Modify -> Change Parameters to adjust insert diameter, bit diameter, clearance, lip, and rib dimensions as needed.
