The Stilt goes through the hole. Glue the Stilt into the Plate. Then put the Roller on the Stilt - it should move freely. Put the Top on the end of the Stilt - done. Print each part speratly so you don't get spilkes from the retraction. I printed mine with PLA, 210°C, 75 Bed, 50mm/s, 0.1 Layer Height, 0.3 initial Layer height and 100% infill.<br><br>Happy printing!
