Before ordering
Clear square.
Solid start.
The current support has a nominal 58 by 58 mm CAD base. Print the footprint. Check the whole floor path.
Planning only. Not physical fit, height, contact, load, or safety proof.
Print at 100 percent
Measure the ruler first.
The printed line must measure exactly 50 mm. If it does not, stop and correct the print scale.
Cut outside the solid 58 mm square only after the ruler check passes.

Print. Verify. Place. Remove.
Verify 50 mm
Print at 100 percent. Measure the ruler line with a physical ruler.
Check the square
Use a hard, flat floor. Stop for a fan, grille, filter, cable, screw, soft surface, slope, or unknown area.
Remove the paper
Remove the card before restoring power. Then run the height and contact checks.
Use boundary
A clear paper footprint does not prove the exact printed part fits, reaches the GPU, contacts a safe structure, carries a load, or is safe for the system.

Nine indexed design stops. No shims. No forcing.
