modified fs-cover-mmu2s

<p>A modified fs-cover for the mmu2s upgrade that attempts to solve the IR sensor issue.</p> <p>The original model is modified by adding a small tab to the left side which accepts an M3 standard nut and screw. The screw pushes down on the extruder, causing the IR sensor tower to tilt allowing for fine adjustment of the sensor trigger.</p> <p>I was unable to source the original brass hardware so the hole for the hardware which accepts the festo coupling was modified to accept the M5x6x7 threaded insert which can be found in this kit on amazon:</p> <p><a href="https://www.amazon.com/gp/product/B07WH59N6T/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&amp;psc=1">https://www.amazon.com/gp/product/B07WH59N6T/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&amp;psc=1</a></p> <p>3MF file is set up for PLA which is what I had on hand when I printing this part. It appears to be holding up fine for the near-continuous printing I have been doing for the last week. I will reprint in PETG if (when) it fails.</p>
