Screw hider / end cap for a 15mm diameter hole

thingiverse

You need a screw hider or end cap for a 15mm hole. The inner circle diameter actually measures 16mm. This is done so that pressure can be applied directly to the plastic when inserted into the hole. It effectively keeps it firmly in place. Instructions The ABS model was printed on a Kossel Clear with a layer height of 0.1mm, traveling at a speed of 20mm/s and equipped with a brim (I'm currently using Cura as a slicing tool). Initially I had reduced the speed to 42mm/s, however this produced an uneven inner circle, so it was then lowered further down to 20mm/s whereupon the model printed out perfectly on my Kossel Clear delta printer. It takes roughly eight minutes to complete. Experiment with different settings or stick with what you have.
