Redesigned mounts using set screws to fasten 10MM smooth rods.
Much more sturdy than stock 8MM design. Takes 370MM x 10MM
smooth rods. I've added my J-Head and extruder motor mount and an X belt tensioner to the X Idler and an adjustable Z endstop holder. The Idler mount now has "Smooth Rod" through holes so that the rods can be slid out to access the center section without disassembling the printer. The slot in the Idler for the belt bearing screw has a break out panel that must be snapped off before assembly. Filament tension arm uses a 14mm bearing. J-Head mounting holes are 6-32. Mounting holes in center block are 8-32. Set screw holes for 10mm rods are 6-32 (top) and 4-40 (bottom).
Uses (2) 19mm x 55mm x 10mm and (2) 15mm x 45mm x 8mm
bearings. Do not over tighten the set screws.
