<p>remarks:<br />
I did not understand the meaning of &ldquo;1.1 mm&nbsp; puffing &rdquo;.&nbsp;<br />
I made the height as low as possible for being hollow.<br />
I attached 2 Dxf files and 4 stl files.&nbsp;</p>

<p>I also did not understand the white-black pattern on the piece.<br />
If you could explain it for me, I will modify.</p>
