BRIEF DESCRIPTION:

Files herein provide Tabard-Cossa Lab 2x2 nanopore array cells.
Included are the .step files that describe CAD geometry and .stl mesh files for 3D printing for cells that accommodate 5mm x 5mm x 200-300um thick nanopore chips with 4 symmetrically arranged membranes.

Chip dimensions: 5x5mm (+0.1), >0.2mm thick, 2x2 membranes, 2mm array pitch
Rubber gasket dimensions: 5x5mm (+0.2), 0.38-0.48mm thick, 2x2 1-1.2mm openings, 2mm array pitch

Versions included: 0.3S revision 4 (Lowres prints, 2022), 0.3S revision 5 (Highres prints, 2026)
-> low resolution 3D print files are suitable for general resin printers (Form 2/3 tested) with standard resolution resins (Formlabs Clear or Tough1500, <0.2mm tolerances)
-> high resolution 3D print files are suitable for high resolution LCD/DLP printers (Elegoo Mars 8k/Saturn 16k, Cadworks3D Profluidics 285D) with high resolution resins (Elegoo Standard 8k, Ameralabs AMD-3, <0.06mm tolerances).
-> STL and STEP files of individual components and assemblies are included

Archive contents:
-> Highres Print (Elegoo Saturn Ultra 16k) folder - contains high resolution print STEP geometry and STL mesh files, sample print settings
-> Lowres Print (Form 3) folder - contains low resolution print STEP geometry and STL mesh files, sample print settings
-> Gasket punch locator folder - optional tool, high resolution hole locator tool 3D print files for 1.4mm or 1.5mm OD, 1-1.2mm ID biopsy punches for punching appropriately-spaced access holes in rubber sheets
-> Gasket mold folder - optional tool, high or low resolution 3D print mold for casting gaskets out of RTV silicone or PDMS
-> 4x screw cell BOM v0.3S.xlsx and 4x screw cell BOM v0.3S.csv - bill of materials with comments
