Bed Puller

Notice :
The bed puller has been designed with FreeCad (https://freecadweb.org) and the source file is given to be redesigned, adapted, hollowed or improved.
Pulling the support of the bed and not the bed itself, without using the screws of the bed, avoids to induce movements between the bed and the support.
Its size is defined for an Alfawise U20 printer, but may be compatible for other printers having a 310mm bed, but depends on the shape of the support.
The use is completely free, with absolute no warranty of any kind, and my will is that it is kept free.
Usage:
Print the object. The object is oriented so that no support is required.
Mark and drill 2.5 mm holes on the support of the bed.
Screw with self tapping 3mm screws.
