Small, fast, ad-free calculators and utilities from the Hark Tech workshop bench. More on the way.
Tools & downloads
Free utilities you can use without signing up — calculators, an STL price estimator, and the K2 Printer Backup app for Creality K2 owners.
One-click backup and restore for the Creality K2's Klipper config. Free Windows app, single zip per backup, automatic Klipper restart.
Decode 4, 5 and 6 band resistors, or reverse-lookup from a value like 4.7k or 2M2 to the band sequence.
Drag-drop an STL, G-code or 3MF file. See the model, print time, filament weight per colour, plate breakdown — runs in your browser, nothing uploads.
Upload a 3D model and get a printing quote in seconds — volume-based pricing, PLA or PETG, no account required.
Open source
Tools and research I've written for my own workshop and released open source — mostly Creality K2 and Klipper-related. Fork them, file issues, send pull requests.
Klipper Adaptive Meshing & Purging, forked and adapted for the Creality K2 with a one-line auto-installer. Skip the manual patch-and-pray.
True adaptive bed mesh on the Creality K2 by bypassing Creality's closed-source prtouch_v3_wrapper.so. Probes only the part footprint, not the full bed.
Research notes, protocol docs and tooling from pulling the Creality K2 firmware apart — useful if you're trying to get real Klipper freedom on the K2.
OrcaSlicer with native Creality K2 support — LAN auto-discovery, CFS filament-slot sync, and 191 K2 filament profiles imported. Two PRs open upstream; help us validate them for merge.
Ready-to-flash Klipper config for the Sunlu S9 resin printer using the BTT SKR Mini E3 v3 board. Drop-in starting point if you're converting an S9.
