Combining three Zebra pens to make one all-metal gel-ink EDC pen. Start with a Zebra F-701 Stainless Steel Pen: Replace crappy ballpoint refill with Zebra G-301 (gel ink) refill. Replace plastic clicker mechanism in F-701 with a steel/brass one from F-402 (freeze 30 mins, heat with lighter 20 seconds) and unscrew. Now you have an all metal, inexpensive, gel-ink EDC pen! #make #diy #hack #hacktheplanet #penstr
