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.
