I made these feet for my DIY downfiring subwoofer, I found commercial solutions lacking and printed solutions non-existent (at the time of creation, by 2025 this changed).
There is two variants -
- 50mm total height (shown in the graphic)
- 70mm total height (not shown, but same base/tip diameter, just longer)
These feet work for subwoofers as well as other speakers, but depending on what you do they might even fit furniture pretty nicely.
To get some dampening, I decided for a two-component system with a solid base (e.g. printed in PLA or PETG) and a tip made of TPU. This tip also hides the screw, so it is invisible from the outside, three little nubs hold it in place (but it's easy enough to remove with a small flathead screw driver). This allows for a little splash of colour-contrast, but both printed in black will also look fine. The base features a little locator-hole for an M5 grub screw or 5mm dowel, this way the foot can't unscrew itself; this is completely optional though. The complete dimensions can be seen in the attached screenshot.
On the 50mm height variant, the screw will stick out after 40mm, so in most cases 45-50mm total length will suffice. On the 70mm height variant, the screw sticks out after 50mm, so I would recommend a total length of at least 60mm (langer foot=more leverage). Either one needs a countersunk head. M5 or 5mm wood screws work fine, any imperial equivalent should work as well.
printing advice
How solid you have to print these depends a bit on the load and how many feet you will install. As they get loaded from the top we don't get issues with printing orientation, and the screw adds stability as well.
I recommend gyroid infill of around 25-30% for the base - the TPU tip should be gyroid as well, depending on the shore value of your material and the dampening you prefer an infill of 40-50% might be a good starting point, but you may have to tweak it to your taste.
The files are already oriented in proper print-orientation; no supports needed! Your printer will handle these small bridges :)
Print as coarse or fine as you like.
