RE: How to get more out of your 3D Printing filament!
If you had any totally empty spools of the same brand filament you would be able to find the weight of the spool. Then on any other same brand filament, you would not need to take the remaining filament off the spool. Just weigh the whole thing then subtract by the weight of just the spool.
This could be slightly inaccurate as spools weight could change, but I would think it would be almost none if any. I have a bunch of empty spools lying around that I may weigh to see if they are different weight.
Yes, you are correct. I didn't do this because the small coils need less space and you want to have a scale that is very precise between 20-100grams. Spools often wight more than 250+ grams. With this you end up in a higher range and finding there precise scales is more expensive.
Did not even think about the added space the spools would need. Good point! However, the weighing with the whole spool would still be useful even if it was about half a spool left since I often do fairly large prints.
yea good point... currently my 3d printer of choice would be a Prusa MK3 they just stop when the spool is empty and you can insert the next one! In this case you only have to worry if you have one more on the shelf or not :)
I would love the MK3, currently have an MK2 though. Thinking about the MK2.5 upgrade, but really want to upgrade to the MK3.
