Your W123 never had a cabin filter from factory. Dust, pollen, and exhaust fumes come right through the vents.
I fixed that.
This is a digital DIY kit inspired by classiccarstoday.ruproducts — but you get instant download, no shipping.
What's included:
- STL file of the filter frame (print in PETG/ABS)
- Material guide — what to print with
- Filter element description
- PDF installation guide — step-by-step, with photos
You only need:
A 3D printer + basic tools + 30 minutes.
Why this instead of buying a ready-made filter?
- No waiting for delivery outside Russia/CIS
- You can reprint if broken
- Total cost ≈ $5–7 per filter (after first print)
How it works:
Pay once → download files → print → install.
