Bobbing along on the crest of a wave - Classic 3DBenchy Another make as part of the November printing event https://www.crealitycloud.com/contest/november-3d-printing-event and taken from the current leaderboard. Calibration tools are essential for accurate printing, especially when using a new printer or new filament that you have not used before. I have made a few calibration models myself but still use the 'classics' like the calibration cube and the fabulous benchy along with my own calibration model the Small Rocky the Rocket Ship that was designed as a calibration tool for the next generation of printers. The benchy boat is great for checking layer shift, speed, heat and overhangs. Easy to print with no supports required and really help to get your settings dialled in. Although I have made some of my own calibration models I will always tip my hat to the true creator of the 3DBenchy These were printed on one of my K1 Max's. Sliced in Creality Slicer with the following settings: 0.4 Nozzle 0.2 Layer Height 20% Infill No Supports or Brims (that's cheating) The orange one is printed in Eryone PETG and the Silver one is printed in Polymaker Silver PLA [%2443000667][%9631304319][%6839402488][%9437581472]
