XY Bracket Replacement for Robo3D R2 Printer
thingiverse
My R2 seems to be really hard on the XY Brackets. 3 have cracked already and new clam shells from Robo3D sometime break off tabs while installing. Robo3D Technical Supports tells me that they no longer have any XY Brackets and will not be getting anymore. I down-loaded the "R2 C2 Screw Together Brackets.stl" from the Robo3d Community http://community.robo3d.com/index.php?threads/r2-c2-linear-rail-bracket-ends.19536/ I modified the design to recess the screws into the bracket because the screws will hit the extruder motor if used on the rail at the back of the printer. I put the screws on the outer edge so the post for the belt tensioner spring is solid plastic and hopefully stronger. Better make some spares now.
