Replacement Tabs for Biometra PCR Machine

thingiverse

Someone in the lab, needing a replacement part for their broken PCR machine, requested my assistance due to my 3D printer access. The item required was a flat black rail used as a lid interlock to hold the heated lid down on samples during PCR. After measuring the dimensions of the original part and its screws, I designed a substitute in OpenSCAD. Although not as robust as the original, it's cost-effective as repair expenses often surpass new machine prices. To extend the machine's life, I plan to print 20 of these parts. The PCR machine in question was a Biometra T-gradient, crucial for 96-well plate PCRs and its heated lid prevented sample evaporation. The Gcode file is compatible with any printer at 220C and requires beveling the tab edges using scissors or a sharp object after printing. While recompiling the STL from OpenSCAD to make it thinner might help, I found it unnecessary for my needs.
