ColorFabb empty spool weight (tare)
An empty ColorFabb spool weighs about 235 g — that is the tare to subtract from your scale reading before trusting it. At 0.335 meters per gram of 1.75 mm PLA, ignoring it overestimates your remaining filament by ~79 meters. The spool remaining calculator applies this exact preset for you, and the full brand-by-brand table lives in the empty spool weight database.
235 g
empty ColorFabb plastic spool — ≈ 79 m of 1.75 mm PLA
| Brand | ColorFabb |
| Spool type | plastic spool |
| Empty weight (tare) | 235 g |
| Equivalent length of 1.75 mm PLA | ~79 m (at 0.335 m/g) |
How to use this number
- Weigh the spool on a kitchen scale with 1 g resolution (not a bathroom scale — they are inaccurate below a few kilograms).
- Subtract the tare — scale reading minus 235 g gives the remaining filament in grams.
- Convert to meters — multiply grams by 0.335 for 1.75 mm PLA, or use the filament length to weight calculator for other materials.
- Skip the math — the spool remaining calculator does all three steps with the ColorFabb preset and shows grams, meters and percent left.
About this value
ColorFabb ships on a heavy plastic spool. These are community-measured approximations for standard 1 kg spools (compiled by spool trackers such as filamiq and sigmafilament). Manufacturers revise spool designs without notice, so real weights drift by tens of grams between batches — weigh your own spool if the exact number matters.
Frequently asked questions
How much does an empty ColorFabb spool weigh?
About 235 g for the standard 1 kg plastic spool. It is a community-measured approximation — batches and spool revisions vary by tens of grams, so weigh your own empty spool if the exact number matters.
How do I calculate how much ColorFabb filament is left?
Weigh the spool on a kitchen scale, subtract the 235 g tare, and you have the remaining grams. Multiply by 0.335 for meters of 1.75 mm PLA — or let the spool remaining calculator do it with the ColorFabb preset built in.
Is the ColorFabb spool tare exact?
No. These are community-measured approximations and manufacturers change spool designs without notice — weights can drift by tens of grams between batches and revisions. For an exact figure, weigh an empty spool of the same brand and revision yourself.
What happens if I forget to subtract the ColorFabb spool weight?
Your scale overestimates the remaining filament by the full tare: 235 g looks like ~79 meters of 1.75 mm PLA you do not have — easily the difference between a finished print and an overnight failure.
