- 4. MACSBUG, thank you very much for your help Today’ theme is “The Case of expansion module” https://macsbug.wordpress.com/
- 6. I apologize first. Jimmy, I‘m sorry！ However, I am not malicious in your design.
- 7. Case for the expansion module issue •Many people want the case to fix expansion module • "M-BUS" connector is susceptible to stress and prone to contact failure •Although "data for 3D printing of the case" is released on GitHub ... • There is no environment for 3D printing • Output result is depend on the performance of the 3D printer • 3D printing services such as DMM.make are a bit expensive I want to do “as easy as possible”
- 8. M5Stack Genuine Case At first I make data with shape as it is
- 9. Output Result Optical Modeling(OBJET) FDM(AFINIA H480) AFINIA can not output thin wall…
- 10. Corner of genuine PCB It is difficult to make with FDM printer The thinnest part is less than 0.4
- 11. Modify the outline of PCB M5Stack Self made
- 12. Modify the outline of PCB M5Stack Self made Round corner Move 0.3 mm inward at the part contacting the rib of the case
- 13. Result of outputting modified data AFINIA H480 Board mounted
- 14. Output result on various models uPrint (JPY3,000k) AFINIA H480 (JPY180k) DMM.make 3DPrint (JPY1k/pcs) ANYCUBIC KOSSEL (JPY28k) DMM.make akiba Sony Creative Lounge I have a sample today, so please talk to me if you are interested 自宅
- 15. Currently split outer frame and holding parts Reduce post-processing work by not need to remove support
