I left the supports on the part (they just need to be cut off
with flush cutters) so you could see what they look like. I also
purposely printed it at a slight angle so you could see the
layer thickness, it's especially noticeable on the flange edge.</div>

<p style="margin-top: 0px; margin-bottom: 0px;">I have
produced one attached this email.

<p style="margin-top: 0px; margin-bottom: 0px;">I think it is
ok what you have already done. We do not need a very high
resolution.</p>
<p style="margin-top: 0px; margin-bottom: 0px;">I would like
to test how stiff it is.</p>
<p style="margin-top: 0px; margin-bottom: 0px;">Clear resin is
ok as well.</p>

Do you already have .stl files for that part? I can
generate those just fine but wasn't sure if you already
had one if you wanted to compare something more directly

DSG has an SLA 3D printer that could be used or if
an extrusion 3D printer is preferred, we can look
into one of JLab's other 3D printers.<br>
