The inner diameter of 0.24 mm is drawn larger than necessary. Ball bearings must be pressed into place when installing them. To ensure a proper fit, screw the M3 screw straight into the bearing as possible, using it as a guide. Once installed, mount the coil holder according to standard procedure, measuring approximately 50 mm (as shown in Picture_04). If needed, refer to page Bauteil1 for adjustments that can be made to reduce its size. Finally, check if the filament coil is moving smoothly along its track. If not, press down further on the next page.
