Potassium Channel KcsA

thingiverse

Potassium channels like those in nerves rely heavily on ions moving through them to function properly. The potassium channel KcsA from Streptomyces lividans is a model for this crucial mechanism, comprising four identical protein subunits that work together as a team. According to scientists, potassium channels allow the passage of potassium ions across cell membranes but block other ions like sodium ions. To bring the potassium channel and its components to life, three 3D files need to be printed out: one set with file names ending in "surf_fixed.stl" and another with "K.stl". Since these files are created at the same scale, they require consistent scaling for accurate results. The model itself is based on entry number 1K4C from the Protein Data Bank (http://www.pdb.org/pdb/explore/explore.do?pdbId=1k4c), and its design was facilitated using VMD software. When working with this 3D printed replica of a potassium channel, make sure to apply the following steps for successful results: Necessary steps: Four "1K4C-surf_fixed.stl" files need to be printed in order to achieve the desired structure. It's worth noting that the models were designed in such a way that each part of it is colored differently, making identification much easier. These printed copies work hand-in-hand with other components created using different file formats. When all necessary parts have been obtained, ensure you have MakerBot Desktop software version 3.6.0 or later installed on your computer and adjust the printer settings as described below. Use supports when printing the channel pieces, in addition to ensuring sufficient layer adhesion and high-quality resolution with good temperature management and adequate infill material density at around 15% of standard density settings
