nondescript_numberline_segment can be used to extend the number line by five units; it connects with other units using horizontal, fixed pegs. Print as many as needed to extend the numberline.

The other segments are labeled self-explanatorily. It is recommended to print:
1x negative_ten_to_negative_six
1x negative_six_to_negative_one
1x zero
1x one_to_five
1x five_to_ten

numberline_peg is movable. Print at least two to represent where one is focusing on the numberline.

During printing, print the pegs with supports. Here's an example, but trial and error on one grid piece may be prudent. After printing, use needle-nose pliers or a dental pick to remove the supports and be prepared to sand the underside if necessary.
| Setting                    | Value                                                           |
| -------------------------- | --------------------------------------------------------------- |
| **Support type**           | "Everywhere" or "Touching buildplate" (preferred if peg is low) |
| **Support overhang angle** | ≤ 50° (to catch the full underside of the peg and ring)         |
| **Support density**        | 10–20% (enough to hold it up)                                   |
| **Support Z gap**          | 0.1–0.2 mm (ensures supports break away cleanly)                |
