Joiner callibration tabs

thingiverse

As a newcomer to 3D printing with just two weeks of experience, you are dealing with joining smaller printed pieces into a larger whole. You've decided on a 10x20x20mm tab-in-slot joint for its rigidity. However, sizing the male end to fit the female end has been challenging due to varying print settings. To make this process easier, you've created tabs with different dimensions that can be quickly tested without printing a complete object. For your convenience, each tab is labeled with its measurements. You are concerned about the curling of the "18, 8" tab on the right side and wonder if it is caused by the lack of a heated print bed. Experienced 3D printers can provide insight on this issue.
