"New" Graber Brazilian project, with a biggest printer area, using a structural aluminium profile that can make it easy to build, the connectors can be printed if you want but you can buy the universal connectors to hold the profile. the bearing and motor support can be printed and hold with M3 bolt. fell free to give us your suggestions and feedback. How I Designed This details Structural aluminium profile profile 20 x 20 mm 4 x 400mm 4 x 300 mm shaft ground 8mm 4 x 400 mm 2 x 300 mm M5 threaded rod (recommended stainless steel rod) 2 x 400 mm M5 threaded rivet 2 x rivet linear bearing LM8uu 4 for Z axis car 3 for X axis car 4 for Y axis car universal connectors 15 connectors for 20 x 20 aluminium profile 4 bearings used to fix the Y axis, can be printed the electronic is the same of a original graber project, I'm using Arduino + ramps in the superior support of the Z axis I used the 608zz bearing so i must to be make adaptation for use with a 5mm rod, if you'll use with a 8mm rod you don't need this.
