CGA 320 Dust Cap

<p>For CGA 320 (aka CGA320, CGA-320).</p><p>The dust cap is threaded so it doesn't fall off easily. &nbsp;It has a finger-friendly hex-like shape at the back for easy turning.</p><p>Some might prefer a remix that doesn't have threads and instead relies on layer lines to stay on but can be pulled off all at once. &nbsp;Not sure how easy it'd be to tune that to fit well enough, but the .f3d file is included in case anyone wants to remix.</p><p>I think PETG is a bit better for this than PLA, if only for the better impact resistance if somehow the cap gets bumped into something. &nbsp;But either should work fine.</p><p>For slicing, Arachne works great for this (PrusaSlicer 2.5 or Cura 5). &nbsp;Pre-Arachne might not work so well since it's thread on the inside of a thin wall. &nbsp;Yay for Arachne!</p><p>The 103 percent in xy is to loosen up the threads a bit. &nbsp;At 100 percent, it's a challenge to screw it on more than a few threads. &nbsp;At 102 it'll go on there, but way tighter than necessary. &nbsp;At 103 percent it's just loose enough to turn quickly. &nbsp;At 104 percent it's a bit wobbly but still works fine. &nbsp;The STL has the 103 percent in xy baked in so hopefully it'll just work for most.</p><p>0.2 layer height works to print the threads - probably 0.3 height would struggle.</p><p>&nbsp;</p>
