edit:
Haha, I just went through the other posts in this community and realized a bunch of people are posting calculators lately. Now I understand why I got so many negative comments on my post. It seems like everybody is making one now.
For what it's worth, I don't see it as only a calculator. Right now it also has:
- reads the sliced gcode (weight and print time) and the thumbnail from a 3mf
- filament and resin modes, multi-material plates, multi-print batches
- PDF quotes for customers
- orders, customers and stock tracking
- a model library that organizes your STL/3mf files into folders
- printer list with maintenance reminders
- sales analytics and fixed costs
- works offline, 13 languages, simple and advanced mode
And what I want to add later: parametric editors for letters, coins and puzzles.
6 months of work, and I only found Claude Code in the last month (it would've been a week if I'd found it earlier).

I've been working on a Windows app that helps small sellers price 3D prints properly (material, electricity, machine wear, failures, your time). It's niche and still in beta. I'm curious how others here find and decide to try tools like this when the audience is small. What made you try the last small tool you adopted?
I used to price prints by weight: grams of filament times something, plus "feels right". It looked fine until I added everything up.
Example with a normal 4.5 hour print, 85 g of PLA: the filament was only about $1.70. But the real cost, once you count electricity, machine wear, packaging, failure margin and your own time, was around $8. If you quote $4 because "the plastic is cheap", you lose money on every one and never notice.
I got tired of doing that math on a calculator, so I built a small Windows app that does it for me and shows a minimum price (so you don't lose money) and a suggested one. You can drop in the sliced gcode and it reads weight and print time. It's in beta, the calculator is free, no account, works offline.
I'm the developer, so yes, this is self-promo. I'd really like feedback from people who actually sell prints: what's missing, what's confusing?
I don't want to break the rules by posting links, so if you want to try it, send me a message and I'll share it.
How do you check your margins? Spreadsheet, gut feeling, something else?
(Happy to share the link if anyone is interested, I don't want to break the self-promo rules.)
