XL Long bed 3D-printer conversion

This how-to will show how to fit a longer bed on any flashable 3D-printer. We use the long bed ourselves to print windturbine blades.

    1. Weld or bolt together the aluminium profiles so they are connected and make a platform of 1m * 20cm. Preferabbly this happens on the ends only so they are not skewed or distorted by the welding process.

    2. Drill holes for the bearing holders. They should be 1m apart.

    3. Install the bearings approximately 5cm from the bed. By now the set-up should look like this:

    4. Put the glassfiber sleeve over the NiCr heating wire and pull it through the hollow spaces of the aluminum bed

    5. (Recommended) Put some glassfiber cloth at the end of each alumium profile so the air stays inside
