Bigger mendel but cheap

yet an another mendel, build from inexpensive square aluminum tube easily found in the local hardware shop, bigger than the regular one but not too big (40cm*40cm*50cm. but stronger (10mm smooth and threaded rod) vertical X installation to allow easy acces to extruder, enough room to install dual extruder

print size to be 31*28cm 25-30 cm high depends of the hotend size
