Front assembly

1. Cut the Signo Broad cap to 4.5 cm.
2. Disassemble the Grip Matic and cut its barrel as illustrated. Do not cut the lead tube.
3. Cut two Grip Matic grip stripes for each of the two pieces. Fit the stripes over the Grip Matic tip and barrel, joining the parts with an insert as shown.
4. Cut 3.5 cm from the back of the Grip Matic lead tube. This completes the front assembly.

Body and retractable mechanism

1. Disassemble one G2. Wrap it with two or three layers of clear tape, or one or two layers of electrical tape. Cut or file 4 mm from both ends and insert the assembly.
2. Remove the plastic tip from the Baoke cap (or ColorTwin substitute). Disassemble the second G2 and place its spring inside that plastic tip.
3. Remove the Airfit ink tube and cut 2.5 cm from its back. Wrap tape around the tube 3.2 cm from the front to stop the spring.
4. Widen the Baoke/ColorTwin plastic tip so the Airfit tube can pass through freely. Assemble the retractable mechanism and wrap it with three or four layers of tape.

Cap and finish

1. Disassemble the G3 and keep its tip and cap. Use one section of Grip Matic grip to hold the G3 tip inside the cap.
2. Put the G3 cap assembly onto the retractable mechanism and add a G2 grip.
3. Decorate with electrical tape.
