Parametric Agarose Gel Comb
prusaprinters
Customizable comb for agarose gels. The included STL is a BA-14 1.5mm thickness. However if you have the measurements for any comb, download the Fusion 360 file. Once in Fusion 360 you can customize the parameters to fit any desired configuration. I run a teaching lab and was shocked that combs cost ~$80 each so I designed this to print for a few cents. I have tested it with PLA and they work remarkably well if the agarose is poured at ~50°C. If you wanted to be extra sure they can stand the heat you could try printing in PETG. Variables to Specify in Fusion360:NumTeeth: Number of wellsToothGroupLength: length from the left of the first tooth to the right of the last toothToothThickness: The thickness of the tooth (i.e. 1.0 or 1.5mm)BaseLength: length of the entire comb including the slots at the end which hang on the casting trayGapWidth: The gap between the wells. 1.831mm seems to be the standard, I would leave this value alone.
