chinese cnc3040 spindle upgrade parts
thingiverse
this print used for chinese cnc3040 spindle 300w upgrading to 1.5kw i feel my chinese cnc3040 spindle is weak to carving hard wood or aluminium so i upgrade the spindle 300w to 1.5kw some people cut the part and welding spindle clamp to z zxis carriage. this method is not cost and not damage to original parts. so i use this 3d print to replace it. simple and cheap. 80% infill print is very firm to resist almost 10kg in my experience(bicycle stand) i guess (1.5kw spindle+ spindle clamp + carriage plate) weight is under 5kg check the z carriage picture (this model linear bearing size 12mm ; LML 12UU)
