Printed out fine and exactly what I was looking for

This tool should be in everyone's tool kit. simple solution to estimate remaining filament. I scaled the depth down so that it fits nicely in the narrow drawer in my toolbox. I can't speak to exactly how precise it is, but it's definitely close enough to get a general idea of remaining volume left on the spool without removing it from the AMS.

nice design.. mines messed up but that was due to textured plate. Will reprint and update

Very useful little tool. Simple to print and gives a great guide. I now use it all the time.

I was able to improve the speed (2h => 1h) and filament usage (46g => 31g) of your print model, and allow full gram amounts to be printed with 0.4mm nozzle. I added a print profile so you can take a look. What I did was: 1. Printed face down, reducing the purge tower to a minimum (significantly reducing filament used) 2. First layer is printed slowed down - for accurate results on the print face 3. First layers with reduced print width - for increased accuracy (allows full numbers on 0.4mm nozzle) 4. First couple of layers are 100% infill, so you it doesn't look transparent, and you don't see the infill pattern inside 5. First layers with 0.08mm layer height, for increased accuracy. All subsequent layers are with 0.28mmm layer height for increased speed

Great idea. Very useful.

Great idea, especially for measuring in the AMS, it's really very useful. (3 walls, gyroid infill 5%, 0,4 nozzle, 0,2mm layer)

Great print, 3 walls, adaptive cubic infill and no primer tower with 0.4 nozle
