All Tools
Every free tool and reference in one place — diagnostics, calibration, print prep, model analysis, and more.
E-steps Calculator
Measure your actual extruded length and get the corrected steps/mm value for your extruder motor.
Flow Rate Calculator
Fine-tune your extrusion multiplier using a single-wall test cube measurement for accurate walls and infill.
Temperature Tower Analyzer
Describe your temp tower results and get a suggested ideal temperature for your filament and printer combo.
Retraction Test Tool
Dial in retraction distance and speed settings to eliminate stringing and blobs from your prints.
Pressure Advance / K-factor
Tune Pressure Advance (Klipper) or Linear Advance (Marlin) for sharper corners and cleaner line starts.
Max Volumetric Flow Calculator
Find the highest safe print speed your hotend can handle before under-extrusion sets in.
Print Time Estimator
Upload your G-code file for a more accurate time estimate — factors in acceleration overhead, travel moves, and layer count.
Layer Height Optimizer
Find "magic number" layer heights for your leadscrew pitch to minimize Z-wobble and banding artifacts.
Support & Infill Optimizer
Get recommendations for minimal support settings and infill patterns balanced for strength vs. material savings.
STL Analyzer & Repair
Upload an STL to detect non-manifold edges, inverted normals, and holes — with one-click repair suggestions.
Wall Thickness Checker
Scan a model for walls too thin to print reliably with your nozzle diameter before you waste a print.
Model Orientation Calculator
Find the optimal print orientation to minimize supports, maximize part strength, or fit your build plate.
Filament Cost Calculator
Figure out exactly how much each print costs based on spool price, weight, and estimated print usage.
Settings Cheat Sheet
Recommended temperature, speed, and retraction settings for PLA, PETG, ABS, ASA, TPU, and more.
Filament Drying Guide & Timer
Material-specific drying temperatures, humidity targets, and a built-in countdown timer to dry your filament right.
Nozzle & Hotend Compatibility
Check nozzle compatibility for your hotend and see max flow rates and abrasion-resistant options for filled filaments.
Spool Weight Estimator
Weigh your spool on a scale to calculate remaining filament length and estimated print time left on the roll.
Filament Diameter Variance
Log multiple diameter measurements across your spool and get flow compensation suggestions for inconsistent filament.
G-code Viewer & Simulator
Visualize your sliced G-code, simulate the print path layer by layer, and spot potential issues before printing.
Custom Test Print Generator
Create tailored calibration prints — stringing towers, tolerance tests, overhang benchmarks — tuned to your exact setup.
Firmware Settings Compare
Compare Marlin or Klipper config files side by side, or generate recommended start/end G-code snippets for your printer.
Multi-Material / AMS Planner
Plan purge volumes, color order, and waste minimization for multi-filament and AMS setups.
Slicer Profile Generator
Input your printer model and filament type and get a starter slicer profile for Cura, PrusaSlicer, or OrcaSlicer.
3D Printing FAQ
Quick answers to print questions, tied into the diagnosis tool for guided troubleshooting without the guesswork.
Test Print Library
Free curated STLs for calibration — temp towers, retraction towers, overhang tests, stringing benchmarks, and more.
Print-in-Place Models
Beginner-friendly articulated models that print fully assembled — no supports, no post-processing, just peel and play.
