Ender 3 Top Rail Holder for Smoke detector

thingiverse

Update: Version 2 now available. -Rail mount is now a separate component with a clip, allowing for easier modification of the Arm. -The arm features a hole that securely holds clips from the rail mount in place. - To address inflexibility issues with the little holders, I designed a tight-fitting slide-on adapter. Ensure exclusive sizing when printing this design. This design has been successfully printed and tested on an Ender 3 using a 0.12 layer height with supports. My first Fusion 360 design. Since I haven't updated my Ender 3's firmware for thermal runaway protection, I wanted to add an extra safety layer while at home but away from the printer. This is a simple rail slide in design. Feel free to edit and customize as needed. A step file has been included for editing purposes. The print was made using PLA at 205°C. Note: This design is not intended to hold significant weight. For added stability, consider solidifying the middle beam.
