SummaryReplacement flag pole fennel (top) for a household pole that holds a 4ft x 2.5ft flag. When printed at 100% scale the inner diameter is about 25mm I would suggest scaling up or down a bit if your pole diameter is significantly different. The old wood fennel on our pole rotted and fell apart the pole itself was fine so rather than buying a new pole I modeled and printed a replacement fennel it's not a perfect replica but it's close enough to get the job done :) If you want to make adjustments you can make view and copy this model in OnShape here: http://tinyurl.com/hfwbbuv
