Pen Lift Guide Frame
This C-frame is the pen-lift guide for the 'NEMA17 Cantilever Pen Plotter' kit. It bolts to the pen shuttle's M3 heat-set grid (20 x 20 mm) with four M3x10 screws. Two 4 x 55 mm steel guide pins press into its 6 mm arms 24 mm apart, and a 16 mm pen pass hole runs between them. An SG90 servo fits a 23.5 x 13 mm window with slotted tab holes that take 26–31 mm tab spacing. The frame measures 78 x 58 x 25 mm and prints flat on its backplate with no supports.
Pen Carriage LM8UU Shuttle
The pen carriage for the 'NEMA17 Cantilever Pen Plotter' kit. The 48 x 63 x 37.5 mm shuttle rides two 8 mm X rods set 40 mm apart on two LM8UU bearings, which press into 15.05 mm pockets against a stop face, and a 14 mm belt channel stays open underneath. Both GT2 belt ends pass through 1.6 mm slots in stiff lugs under the deck and fold back on themselves. The flat front face has four M3 heat-set bores on a 20 x 20 mm square for the pen-lift frame.
X Arm Tip Idler Roller
The far-end block for the 'NEMA17 Cantilever Pen Plotter' kit's X arm, about 54 x 57 x 74 mm. It clamps the ends of two 8 mm rods set 40 mm apart in 25 mm pinch sockets (M3x16 screw plus a captured M3 nut in each). Two cheeks hold a 608 bearing as the GT2 belt idler on an 8x25 mm dowel, locked by an M3x10 self-tap screw. Below, a fork carries a 624 bearing on an M4x20 axle in a height-adjustable slot, so the arm tip rolls on the desk and can be levelled. It prints upside down, standing on the flat tops of the cheeks and clamps.
Y Carriage LM8UU Sled
The Y carriage for the 'NEMA17 Cantilever Pen Plotter' kit: an 84 x 80 x 30.5 mm sled with four LM8UU bearings pressed into 15.05 mm pockets. It rides two 8 mm Y rods set 60 mm apart. A 6 mm top deck has an M3 heat-set grid (40 x 60 mm) for the X arm root block. Two posts under the deck anchor the GT2 belt ends, and the 14 mm belt channel stays open.
Y Motor End Block
The Y motor end block for the 'NEMA17 Cantilever Pen Plotter' kit. It anchors two 8 mm Y rods at 60 mm spacing in 25 mm deep pinch-clamp sockets, each tightened with an M3x16 screw and a captured M3 nut. It also holds the Y NEMA17 on a 5 mm vertical wall (31 mm M3 bolt square, 22.4 mm teardrop pilot hole) and sits on the desk as a 102 x 77 mm foot. The base is pocketed to save material, and the GT2 belt channel between the sockets stays clear.
