Doorman with fixes and improvements

thingiverse

The original doorman design was a fantastic concept, but unfortunately, it had several flaws that needed to be addressed. A major issue arose with the files, which contained numerous errors. In a recent update, I revised the eyeholder v4, carefully lowering the eyeballs by 1mm to enhance clearance between the eyelids and the eyeballs. This modification allows for improved functionality. Additionally, I introduced Mask v2, which features two small shelves beneath the eyes to accommodate Red LED's. To achieve an eerie effect, glowing red eyes are essential. The LED used is available from Amazon (https://www.amazon.com/gp/product/B073YCX8WW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1). It can be configured in various colors, including red, blue, white, or green. Although this design has not been printed yet, it should work seamlessly without the need for supports. This project is still a work in progress, but I am confident that all components will print successfully and function as intended. To cater to users with the Prusa MM2 multimaterial kit, I have included three separate files for the eyes. These can be used in conjunction with manual filament changes or integrated directly into the kit. The eyelids feature a bar that enables them to move together, making it easier to attach to a servo motor. Regarding the PIR sensor, the standard model has a 23mm diameter. If you remove the white dome, the sensor measures approximately 9mm, which is identical to a mini PIR sensor. The hole in the head is precisely 9mm in diameter, allowing for the use of either a mini or standard PIR sensor. To improve printability and prevent an uneven bottom, I separated the doorman face and bottom into distinct pieces. Additionally, I incorporated a Uno holder for convenient access. The eye holder underwent a complete redesign, but it can still be used with some tweaks required. The center servo holder was lowered to enable control over both the upper and lower eyelids. However, the INO control file does not utilize servos 4 and 5, which are responsible for controlling the eyes' up and down movement. Unfortunately, only the top eyelid is currently operational due to a lack of connection for the lower eyelid. To address this issue, I created a custom 3D printed u joint, eliminating the need to search for a specific 3mm to 3mm u joint. In the original design, the bars were too short, but I extended them to ensure a better fit.
