Bassreflex Port / Tube with 60mm in / 225 length

This is a solid bass reflex port i designed for my underseat woofer and calculated necessary diameter and length for the targeted 35-40Hz frequency 

After finished printing, i recommend to refine the surface with a fine sanding paper(pad), starting with 500 and finish it with 1000.

you may vary the length for your needs, but you can reach out to me if you have a request for a specific length or diameter - but keep in mind: most printers top out at ~250mm

tip: Print out the plug in rather TPU or PLA to try out a sealed setup if you want to/need to!

thank you for your support and your consideration
