About this app

3D Printing Toolkit is the offline companion for FDM 3D printing — the calculators you actually use plus a print-defect troubleshooting guide, all on your phone. No internet, no account, no sign-up.

Dial in a new filament, calibrate your extruder, or rescue a failing print at the printer — every number is backed by a formula you can see, so you know exactly what it's doing.

CALCULATORS (all free)

• Filament cost & weight — mass, volume and price per print
• Flow / extrusion multiplier — correct it from a single-wall measurement
• E-steps calibration — rescale your extruder steps/mm
• Volumetric flow — check a speed against your hot end's limit
• Max print speed — the fastest speed before under-extrusion
• Retraction tuning — distance & speed starting points by extruder and material
• Electricity cost — power use and cost per print
• Solid layers — top/bottom layers for a target thickness
• Resize / scale — scale a model to an exact dimension

Every calculator shows the formula it uses and notes its assumptions — no black boxes, no false precision.

TROUBLESHOOTING (all free)

A print defect → cause → fix reference for the problems you actually hit: stringing, warping, under- and over-extrusion, layer shifting, elephant's foot, Z-banding, blobs & zits, ghosting/ringing, top pillowing and poor bridging. Clear, ordered, and honest about when several causes look alike.

ACCURACY YOU CAN TRUST

✓ Formulas derived from first principles, shown in the app
✓ Material densities are editable typical values, never fixed truth
✓ 100% offline — works at the printer, in the workshop, anywhere
✓ No account, no analytics, no clutter

PRO (optional, one-time)

Everything above stays free, forever. Pro is for power users:
• Save your own filament library (measured densities, prices)
• Save printer profiles and load them into any calculator
• Save and revisit calculation results
• Remove ads

Pro never paywalls a calculator or a fix — only convenience features and ad removal.

Spend less time digging through forums and more time printing. 3D Printing Toolkit keeps the math and the fixes one tap away.

What’s new

Out of testing and available to everyone.

Nine offline calculators: filament cost, flow/extrusion multiplier, E-steps, volumetric flow, max print speed, retraction, electricity cost, solid layers, resize. Each shows the formula it uses.

A defect guide with cause and fix for the eleven problems you actually hit, from stringing to ghosting.

Every calculator and every fix is free, and works with no internet and no account. Pro is a one-time unlock: saved filaments, printer profiles, no ads.
