C1-10P Head Arm Doors

thingiverse

This is a head arm door mechanism for the C1-10P head design from TinyP. The door is printed flat and will fit directly into the cavity of the dome with no significant modifications required. Although not screen accurate, this mechanism provides the door functionality without compromising the dome's structure. Once printed, file the main body slots to achieve a very loose fit so that the slider falls out under gravity's influence. A flat washer glued inside the slider adds weight and helps it fall into place, but if loose enough, it won't require additional support. The slider requires a string, needle thread, or fishing line for lifting it open. For actuation, a 9 gram servo is used in conjunction with a stick providing sufficient leverage and rotational distance to move the door to its fully open position, leaving ample space within the dome for lever movement. Due to the slider's light weight, strain on the servo should be minimal. A small hole in the dome allows the thread or line to pass through, representing the only adjustment necessary to the dome. For now, the main body is secured with sticky tape, but four small dots of hot glue will likely be added for a more permanent hold, allowing for future removal if the string breaks. The servo arm and mount are designed to support the 9g servo. The top of the servo mount must be positioned 190mm from the dome's bottom face, as depicted in the images. Printing the design mirrored will allow for mounting on the opposite side if desired. If this mechanism proves successful with your C1-10P model, please post a picture, and I'd appreciate seeing it in action. Happy building!
