Gamepad dome: freeze Rev 4 before you freeze Shore A

A few millimetres of silicone still needs concentric holes and a written revision. Feel samples at 30 / 40 / 50 came after the drawing pair matched.

Earlier files sat next to Revision 4. That is how steel gets cut to last month's hole. The live pack was the matching Rev 4 PDF and STEP. Notes: remove flash, break edges 0.1-0.3 mm, keep the Ø1.4 mm to Ø3.1 mm stack concentric, max offset 0.05 mm, keep elastic return. Sample order: 10 pcs each at Shore A 30, 40 and 50. Production Shore is not locked in the archive we can publish. MOQ 5,000 is a planning number for this dome program — not WYD's soft-tray MOQ 20.

PDF notes and STEP have to be the same rev

2D carries flash and concentricity that a screenshot of the solid will miss. STEP carries the faces you actually tool. If they disagree, stop before steel. Hardness lots then let the buyer feel actuation — compression force, rebound, thin-feature stability — without guessing from a catalog durometer chart.

What to send

  1. Current drawing revision and matching STEP, named the same
  2. Which holes are concentric, edge-break, flash-free faces
  3. Whether you want multi-Shore sample lots before production compound
  4. Program qty (this job planned 5,000) vs first-article qty

FAQ

Which Shore went to production?

Not in the publishable archive. 30 / 40 / 50 were comparison lots.

Is MOQ 5,000 a WYD house minimum?

No. Soft trays here often start at 20. 5,000 was this dome program's planning reference.

Can we tool from an older STEP if the PDF is Rev 4?

No. Mismatched rev is how you buy a second steel insert.

Do not ask us to pick 40 Shore from a catalog while the hole stack is still on Rev 3.
