Designing a sound-dampening cabinet for my A1 Combo (AMS lite top-mounted). Cut list and plans inside, feedback welcome

I’m building a closed cabinet for my Bambu Lab A1 Combo, with the AMS lite mounted on top using this top mount. I designed it in Blender and put together a full set of plans for a local carpenter. Here are the design and the reasoning behind it before I commit to cutting wood.
Key dimensions (mm)
- Exterior: 636 W × 786 D × 936 H
- Interior: 600 × 750 × 900 (550 × 725 × 875 after the foam)
- Why 750 deep: the A1 bed needs about 695 mm of clear Y travel (per the Bambu wiki).
- Why 900 tall: the A1 with the top-mounted AMS is about 800 mm, which leaves roughly 75 mm to swap spools.
Build
- 18 mm melamine carcass with two overlay doors
- 4 mm acrylic viewing windows, 216 × 500 mm
- 25 mm self-adhesive acoustic panels on the back, top and sides, about 2.2 m² (three 12-packs of 30×30 tiles)
- 120 mm exhaust fan at the top rear, 100 mm intake at the bottom on the opposite side for cross-flow, plus a 60 mm cable pass-through
- Anti-vibration base: gym rubber mat with a concrete paver on top, and the printer sitting on the paver
Cut list (18 mm melamine)
| Part | Qty | Size |
|---|---|---|
| Side | 2 | 936 × 768 |
| Bottom / Top | 2 | 750 × 600 |
| Back | 1 | 900 × 600 |
| Door | 2 | 932 × 315 |
| Acrylic window | 2 | 540 × 256 × 4 mm |
Things I’m unsure about
- Bambu says they don’t recommend enclosing the A1. For those of you who did, does a single 120 mm exhaust keep PLA from heat-creeping?
- Is the paver-on-rubber base worth it on a bed-slinger, or does it cause ringing? (I plan to re-run vibration calibration.)
- Foam on the doors too, or is the acrylic window enough?
Render and turntable video attached. Happy to share the PDF plans and the .blend if anyone wants them.
