Dowel Rod Extender
thingiverse
This is an extension for a 1" dowel rod. I needed a curtain rod, and it wasn't quite long enough so I made this. I printed 2 for symmetry. The extender is a total of 4.5" long with a 1" hollow core on the larger end to insert the dowel rod. If 1" is too much, just mark where you need the dowel rod to sit, and stuff with a bit of paper towel and compact until it's tight.
