The $29 flat rate applies to InstaPart requests with less than 100 pins.
For parts with over 100 pins (excluding connectors), we deduct 1 additional credit for every extra 100 pins, but it's only 1 credit for parts under 100 pins. For example:
Parts with 1-100 pins: 1 credit deducted.
Parts with 101-200 pins: 2 credits deducted.
Parts with 201-300 pins: 3 credits deducted and so on.
If your part has over 100 pins, the team will be following up with you by email for the additional credits purchase before proceeding with the model creation.
