Festool cyclone retrofit.

retrofit for old version Festool cyclone.this file included only lower part. you still need to drill 20mm holes in to your original connector and strap it together.any 20mm starp will be ok. I recommend velcro strap from amazon.(https://a.co/d/hNkAI5E)I drilled hole 3mm on the side first and torched knife to connect two holes bigger.
