Download and Print parts The part names are the same as the file names. If you want individual part files, please download them directly or the [Onshape Document](https://cad.onshape.com/documents/6be13b87a3aad01bd61ef6ab/w/86f8cbb4c7b89f36daabaded/e/60b90b400b488f7dba307a1d?renderMode=0\&uiState=6765edde24e35a5f7c804100). #### Plate STL Files for Printing

Print Setting	Right Hand	Left Hand
100% infill Supports required (45 deg threshold, tree support recommended, on build plate only) 0.12mm layer height (if not possible, print at the smallest possible layer height)	XM430_Pulleys.stl	XM430_Pulleys.stl
100% infill Supports required (25 deg threshold, tree support recommended, on build plate only) 0.12mm layer height (if not possible, print at the smallest possible layer height)	XM430_Finger_Parts.stl	Left_XM430_Finger_Parts.stl
35% infill Raft recommended for thumb panel Supports optional (45 deg threshold, tree supports, on build plate only) 0.12mm layer height (if not possible, print at the smallest possible layer height)	XM430_Motorbase_Side_Panels.stl	Left_XM430_Motorbase_Side_Panels.stl
35% infill Supports required (25 deg threshold, tree support recommended, on build plate only) 0.12mm layer height (if not possible, print at the smallest possible layer height)	XM430_Backhand_and_Knuckles.stl	Left_XM430_Backhand_and_Knuckles.stl
35% infill Supports suggested (regular support recommended, on build plate only) 0.2mm layer height	XM430_Motorbase_Top_Front_Bottom_Plate.stl	Left_XM430_Motorbase_Top_Front_Bottom_Plate.stl
35% infill Supports required (45 deg threshold, tree support recommended, on build plate only) 0.12mm layer height (if not possible, print at the smallest possible layer height)	XM430_Palm_Wrist_and_Thumb_Attachment.stl	Left_XM430_Palm_Wrist_and_Thumb_Attachment.stl

## 2. Check Tolerancing ### All Finger Joints The dowel holes may warp during printing, so check that the dowels can fit into the holes (do not push too hard as it may crack the 3D print). These outer dowel holes should fit the dowel loosely. The inner dowel holes should fit more snugly but not require much effort to press in. If the dowel does not fit, use a 2.5mm drill bit to drill out the holes.
