[SKELETON] Articulated Finger Extensions

Read the UPDATES:

- I have ensured that the base part's wall is always thick enough to hold the pins

- I have added one more tooth to the second gear, to avoid accidental gear collision

- I have set BASE_MID_PIN_EXTENSION default to 4mm, so it can either be melted down for a permanent attachment, or cut short to a desired length

- I have added generatornew, which adds an extra, separately printed connector between the middle and distal parts

IMPORTANT: The below demonstration videos depict the flat version, however the instructions are the exact same. Assembly Demonstration

Measurement Demonstration

Parameters FINGER TYPE

- THUMB If enabled, the finger extension will have 2 phalanges, if disabled, the finger will have 3 phalanges.

BODY MEASUREMENTS

- BASE_LENGTH The measured BASE_LENGTH distance, as demonstrated above.

- BASE_WIDTH The measured BASE_WIDTH distance, as demonstrated above.

- BASE_THICKNESS The measured BASE_THICKNESS distance, as demonstrated above.

- TIP_LENGTH The measured TIP_LENGTH distance, as demonstrated above.

- TIP_LENGTH The measured TIP_LENGTH distance, as demonstrated above.

- TIP_LENGTH The measured TIP_LENGTH distance, as demonstrated above.

BASIC CUSTOMIZATION

- MIDDLE_LENGTH The desired length of the middle phalanx.

- DISTAL_LENGTH The desired length of the distal phalanx. (for thumbs as well)

- INNER_PART_WIDTH The width of the components inside the mechanism. (gears, shafts)

ADVANCED CUSTOMIZATION

- WALL_THICKNESS The thickness of all walls, including the hinge wall around pins, where applicable.

- PIN_DIAMETER The diameter of connector pins.

- BASE_MID_PIN_EXTENSION The length of the pins that connect the base part to the finger moving part. The longer it sticks out, the more it holds.

- PIN_OPENING_NARROW_WIDTH_MULTIPLIER The width of the pin hole openings' narrow part as a percentage of the PIN_DIAMETER. The wider it is, the easier to press in the pin, but also the less resistance to keep it in the hole.

- CLEARANCE The distance between parts. (e.g. if the gear is 5mm wide, and the clearance is 0.4mm, then the gear-space will be 5.4mm wide)

- HOLE_CLEARANCE How much bigger should the pin-holes be than the pins. (e.g. if the pin's diameter is 2mm, and the clearance is 0.2mm, then the pin-hole has a diameter of 2.2mm)

- SUPPORT_CLEARANCE The distance between the support and the part it supports. If it is too small, the support will fuse with the part, and not break off easily, if it is too large, the support will not help the part, and the part will sag. It is wise to set the support clearance in relation to the layer height. Since by default I'll use .2mm layers, that is the default of this)
