APS CAM870 mk2 shell with standard depth. In addition, a 30mm and 40mm depth version can be found in the files section. A test cycle of 20 times revealed no degradation in the PETG. Print at your highest temperature to strengthen bonding between layers. The plastic cover is sourced from https://www.thingiverse.com/thing:3011286. print settings: ------------------ No support is required. PETG material is used. Layer height: 0.15 or 0.10 for better outer quality can be achieved. 30% infill is sufficient, as any higher is not needed due to PETG's excessive strength. 1.2mm bottom layers are recommended to provide additional strength. post processing: ----------------- Sand the outside of the shell to ensure smooth cycling. Verify that the bottom ring does not exceed 21mm in width or it will not cycle well. The model's outer dimensions match the original 1:1 scale. Adjustments may be necessary depending on your 3D-printer's specifications.
