<p>I've been on the hunt for the perfect hypersonic grid fin model, and <a href="https://www.prusaprinters.org/social/225959-t4obrien/about">t4obrien</a> has done it.</p><p>I wanted to modify t4obrien's original model to allow the embedding of 608 bearings for flap and pitch motions. &nbsp;After reaching out to t4obrien, he provided me with a detailed model that I could manipulate in Fusion360.</p><p>I created the “base” to allow for pitch rotation of the grid fin, and then I created a “mount” to allow for the flap hinge.</p><p>Painting involved a grey primer coat for the parts, then silver metallic for the grid fin, and flat white for the base and mount. &nbsp;The bearings are press-fit, and the piece was assembled. &nbsp;To add additional realism, I ‘weathered’ the underside of the gridfin and mounts with some carbon-black spray paint to simulate a post-flight condition.</p><p>To complete this project you will need:</p><ul><li>3 x 608 bearings (<a href="https://www.amazon.com/s?k=608+bearings">Amazon</a>)</li><li>2 x M3x12 Socket Cap Screws (<a href="https://www.amazon.com/s?k=m3x12+socket+head">Amazon</a>)&nbsp;</li><li>(Optional) 6 x M3x8 Flat Head Screws (<a href="https://www.amazon.com/s?k=m3x8+flat+head">Amazon</a>)</li></ul><p>&nbsp;</p><p>&nbsp;</p>
