should have made it clear filament costs come from cura, excel is running the printer
@DeanoG60 How long would this print take with your Ender on standard quality Cura settings
Ender_3_Top_Extrusion_Tool_Holder_With_USB_SD_and_Micro_SD_Storage_4701141.zip (1.5 MB)
I’d have to slice it to find out, I’ll do it tomorrow and let you know?
I’m assuming you mean on my ender7? as I’ve also got the ender3 pro as well lol
Both if you can, I just what to compare against mine as it took 5.20hrs to print
I slice with Creality Slicer, which gives me a time to print BUT on the actual printer it takes a lot longer sometimes as much as twice 
my ender 7 will be considerably faster because it’s Core XY
if its the upgrade I’m thinking it is, 5h 20m sounds about right for an ender 3. it also requires supports. it is the tool holder that attaches to the top bar?
this thing:
although I’ve modded that one to fit my ender 7 lol

@SparkyFPV I sliced the file as if I was printing it myself and screen shot the results. I use prusaslicer for my ender3 and crealityslicer for my ender7.
Ender3:
Ender7:
But keep in mind:
This.
it’s only an estimate 
Thanks Deano, why are you using 2 different slices?
Why not use Cura is that not the best?
personal preference mate, I’ve always prefered prusaslicer, but the Ender7 wasn’t supported so I’ve had to use crealityslicer for the ender 7

I want to edit a STL file, I what to alter it like fill in some holes etc and add some text into a print
What you be the best software (free) to do this
Also what are you using to create your own 3D prints
Tinkercad
its basic but does the job 
I am looking for something that can edit an STL file, Tinkercad is basic but may do what I want 
just import the stl into tinkercad
Yeah, I am on it 
Had phantom triggers on my BLTouch for a while now, couldn’t for the life of me figure it out.
Turns out by sheer fluke when I’d installed it the power wires to the hotend had been far enough away to not cause any interference, and during some maintinance they’d shifted in the wiring harness to be right next to one of the unshielded BLTouch lines. If you probed the bed while the hotend was heating, it would trigger the BLTouch.
A few turns of copper tape later (apparently ferrite beads also work, but I’ve had a roll of this stuff for ages and it’s really useful) and it seems like all the issues have gone away. As much as I love this hobby, sometimes the troubleshooting feels like pot luck.
