HO train track support for AFX Track Borders

Slot car track is not wide enough. Borders are necessary and often named: aprons, curbs, and shoulders.

These HO train supports attach to AFX slot car track borders or AFX track with the alternate clip.

Use PETG because the clips for self attachment will break with PLA.

Bambu Studio will fight hard to hide seams inside the clip, so paint the seam on the outside of the clip. Use enough walls to make the clip solid.
