Rod alarm

▼This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printingPlease leave comments using the talk page. The course runs in the Fall semester. It is not open edit.

This rod alarm system was designed to detect losing rod of the MOST Delta - Athena during printing.

OpenSCAD was utilized for Hook and box modeling operations. The MOST-Athena GitHub file repository is located here. The Hook and box assembly were imported into OpenSCAD and the part was designed to accommodate the geometrical constraints of the parts provided to MY4777.

Hook model

The stiffness of the component is driven by the infill percentage. Adjust as necessary to achieve your desired characteristics.

Print Parameters Utilized for Hook and Box:

• Layer Thickness: 0.2mm
• Skin Thickness: 1.0 mm
• Top/Bottom Thickness: 1.0 mm
• Temperature: 180C
• Speed: 30 mm/s
• Flow: 100%
• Infill: 50%

The model is designed to add onto the end effector. Print out Hook qty. 6 and box qty. 3 of the STL and install as shown below.
