Revolver Pen Holder

My take on a revolver pen holder. There a few designs like this out there but nothing suited what I wanted for size and function. A shoutout goes to all those who have designed something like this previously.
I modeled it from a revolver barrel I have on hand but modified it to have 8 chambers that are large enough to hold 3 standard bik pens each. Hold scissors or felt pens it will fit those also.

To complete this you will need to purchase an 8 mm rod that is 120 mm long and a 608 skateboard bearing (608zz etc). Both of these are readily available on amazon aliexpress. You can cut rod to length with a cutting disc on a dremel if you cant find the proper length.
Also have your choice of glue for chamber plugs and holder cap.

Print 8 pieces "pen holder plugs". One for each chamber
