That’s clever! We may do something similar in-house 
. cc @jeff.watchorn @yangcyril.cao @clascclon @nisfisker. For reference @shijing, here is Formlabs’ High Temp resin. You can also see the solvent compatibility, which seems pretty decent for High Temp resin. (aside: you can filter for desired properties using Powders and Resins for 3D Printing | Formlabs, which shows that Rigid 10K is also suitable for elevated temperatures).
@Lilo do you remember who had the CAD file for this? I can ping to ask. It doesn’t seem like any files are available from the Opentrons Labware Library. Of course, there are designs out there like https://grabcad.com/library/96-well-plate-flat-bottom-standard-1 from GrabCAD.
I’m giving the one from above a go with draft resin (EDIT: this orientation made it hard to remove the supports and resulted in damage to some of the wells):
It looks like you can also purchase custom parts using Formlabs High Temp resin from Protolabs Network (xref: prototyping and Where do you buy things? (custom parts, off-the-shelf, internal tools, etc.) - #2 by sgbaird).
It was fairly straightforward to get the quote (SLA printing → upload STL → edit settings and select Formlabs High Temp). The part quote was for 166.18 USD. Note that the model above shows 126.13 mL as the material usage, and this equates to ~25 USD (199 USD per liter of High Temp resin) if you were to print it yourself, though you also have to do the post-processing (wash, removal of supports, and cure) on your own.
