These are exactly what they sound like: eight small silicone gel pads that go under the feet of an X1 or P1 series printer. Bambu ships them as a set weighing about 70 g total, black, roughly palm-sized packaging — there’s no electronics, no adjustment, nothing to configure. You press them onto the printer’s existing feet (or use a printable adapter from the community, which Bambu itself points people toward for a more stable fit) and that’s the entire install process.
What they’re for, according to Bambu’s own guidance, is isolating vibration transfer between the printer and whatever it’s sitting on — not damping vibration inside the printer itself. If you’ve got the P1S on a shared workbench with other sensitive equipment, or you’ve got multiple printers stacked on the same shelf, these cut down how much of one machine’s shaking makes it into the desk and over to its neighbors. That’s a real, if narrow, use case, and for the price (they’re inexpensive) it’s a low-risk add.
Where it gets interesting is the misconception that seems to follow this product everywhere: a lot of people buy these expecting them to reduce ringing or ghosting artifacts in prints, and multiple experienced users (including detailed breakdowns on Bambu’s own community forum) have pushed back on that pretty firmly. Sitting a rigid printer frame on a soft, compliant pad doesn’t damp the frame’s own resonance — if anything it gives the frame more freedom to move relative to the table, which can make ringing on tall prints slightly worse, not better. If your actual goal is cleaner prints, the forum consensus points at slowing acceleration/jerk settings or adding mass under the printer (concrete pavers, sitting directly on the surface, no isolation pad) rather than these feet. So: buy them to protect other gear or reduce desk noise transfer, not to fix print quality.
Physically there’s not much to say beyond what’s in the box: eight silicone pads, black, packaged in a small footprint (around 145 × 100 × 45 mm), the whole set weighing about 70 g. They’re inexpensive enough that this is a low-stakes purchase either way — if you’re on a shared bench or have printers stacked near each other, they’ll do the one thing they’re actually designed for. If you’re chasing print quality, spend the same few dollars’ worth of time in your slicer’s acceleration settings instead, since that’s the lever that actually moves the needle on ringing.
Pros
- Cheap, simple, zero-configuration install
- Genuinely reduces vibration transfer to shared desks/shelves and neighboring equipment
- Useful in multi-printer setups where isolating machines from each other matters
- Low risk — doesn’t affect the printer’s function or void anything by using them
Cons
- Does not reduce ringing/ghosting in prints — that’s a common and understandable misconception
- Can theoretically make ringing on tall prints slightly worse by letting the frame move more freely
- Benefit is narrow: mainly relevant if you care about vibration reaching other things nearby, not the prints themselves
- Community reports of the pads sliding or needing a printed adapter to stay seated properly
