A step-by-step guide to placing the eitech 7x3-hole curved plate Ø 120 mm so it seats cleanly, holds its curve, and stays easy to adjust during a metal build.
Quick answer
Treat the eitech 7x3-hole curved plate Ø 120 mm as a shaped panel, not a flat one: dry-fit it against the frame, mark the two or three holes that carry the load, and fasten those first before closing the remaining holes. That order keeps the curve from fighting the frame and makes later adjustments easier.
Why orientation matters more than hole count
A curved plate with seven by three holes and a 120 mm diameter has a clear inside and outside face, and the curve only seats well when the plate meets the frame along its natural bend. If you flip it or rotate it so the curve runs across the frame instead of with it, the holes may still line up but the plate will rock under light pressure.
Before you tighten anything, hold the plate in place and press along the curve. A correct orientation sits quietly; a wrong one clicks or lifts at one edge.
Where a curved plate earns its place
Use this plate where a model needs a rounded skin, a wheel-arch-like cover, or a curved transition between two flat sections. It is less useful as a purely flat panel, because the bend introduces a gap that flat plates do not have.
If your build calls for a flat surface, a flat plate will seat more predictably. Keep the curved plate for the places where the shape is doing real work.
When to stop and change the plan
If the plate needs force to meet the frame, the frame is probably not ready for it. Adding washers or over-tightening to close a gap puts stress on the curve and makes the plate harder to remove later.
Step back, check that the surrounding frame is square, and only then return to the plate. A curved part should settle into place, not be pulled into it.
Step-by-step: fitting the curved plate
- 1. Dry-fit before fastening: Hold the plate against the frame without screws and rotate it until the curve follows the frame's bend. Check that all seven by three holes sit over open frame holes rather than over solid metal. If the plate only fits in one position, mark that position with a small piece of tape before you lift it.
- 2. Fasten the load-bearing holes first: Insert screws in the two or three holes nearest the tightest part of the curve and tighten them only until snug. Leave the remaining holes open for now. Snug, not tight: over-tightening here flattens the curve and makes the outer holes harder to align.
- 3. Close the outer holes in pairs: Work outward from the fastened holes, adding screws in opposite pairs so the plate is pulled down evenly. If a hole refuses to line up, loosen the nearest screw a quarter turn rather than forcing the plate. A hole that will not align is a signal to adjust the frame, not to enlarge the hole or skip it.
- 4. Check the curve under light pressure: Press gently along the outside of the plate. It should not rock, click, or lift at any edge. If it does, identify the loose edge and re-check the orientation and the frame squareness. Do this check before adding nearby parts, while the plate is still easy to reach.
- 5. Re-tighten and finish: Once the plate sits quietly, go around all used holes and tighten them evenly. Leave unused holes empty rather than filling them with spare screws. Record the orientation you used if the model will be rebuilt; the curve is easy to reverse by mistake.
