Multi-Purpose 6-Axis Articulating Robotic Arm

UPDATE Revision 2.0!!The model has been updated after all the valuable feedback that I have received from all of you in the recent months.The joints are now much more tight with 0.1mm gap between shafts and holes. Moreover, all joints have now been fixed with 3.2mm countersunk self tapping screws. Hole diameter is 3mm for all screws so you can also try M3 screws.Mounting base now features a screw on bottom face to keep the whole structure safe.Gripper base remains the same structure (featuring a pivot pin), while a through hole of 4mm has been added in addition to cut reliefs on the covers, in order to use M4 screw and nut for adjusting friction force. Discover the versatility of this 6-axis articulating robotic arm, perfect for 3D printing enthusiasts! Designed to print on a single plate, this model is easy to assemble using plain screws or adjusted with tape on the axis shafts for optimal friction and a satisfying rotation feel.This robotic arm is more than a showpiece—it’s a functio
