Retraction Test Towers
thingiverse
I typically print this test with z set at 0.5, which is half the normal height. This makes for a fast and simple retraction test. Experiment with different retraction lengths and speeds in your slicer software. The hotend temperature also plays a significant role; cooler temperatures result in less stringy prints. My Rostock Max v3 (with its long Bowden tube) works well with 5mm of retraction at 25mm per second. Try searching online for "retraction settings" along with your printer's model number.
