The printable part should be provided here: https://forum.tiertime.com/t/cetus-printable-parts-includes-cetus-mki-mkii-and-calibration-model/679 But it is not included. A well-intentioned YouTube personality, acting as a promoter, was initially enthusiastic about ditching the Klicky switches and tramming the sliders on the linear rails by brute force against the ends of the rails. However, he later changed his mind. Showing off the damaged belt connector: https://thingiverse-production-new.s3.amazonaws.com/assets/d9/9b/f1/8d/71/beltconnector_worn_out.jpg The picture shows a rounded top surface on the plastic part. It is unclear whether this was a result of wear and tear or if it was the original shape. This is a replacement part for the weak printed belt connector on the z-axis of the Cetus 3D MKII printer. It can also be applied to the older MKI model. However, it needs to be printed from very tough filament. When printing, use PETG or Nylon. ABS may not last long and should be avoided. The part should be as rigid as possible. It would be better to make all dynamically loaded parts from strong steel. Avoid using soft steel, which was used in the motor mounts earlier. This type of steel bent under the force delivered by the spring-loaded belts. Even after upgrading to a stronger material on my printer, the motormountplates are still bent. The belts are not running exactly in the middle of the gears/channels and their path is tilted. Peter120 fights this issue with an additional bracket that mounts the outer side of the z-axis stepper motor tightly to the base plate: https://thingiverse-production-new.s3.amazonaws.com/assets/63/7a/f8/57/2a/Picture_628.jpg They print it from standard PLA, which is a cheap material. Squeezing out the last penny by making critical parts from brittle PLA is not worth the risk.
