Soldering arms V2

Updated model of connectable jointed arms - which can be used as soldering arms, fidget spinner chain, or as miniatures holding arms - https://makerworld.com/en/models/692491-painting-arm-stand-handle Models in this version are more robust, easier to print, bend at much better angle (close 90 degree), and are less prone of sliding off each other. Filament type can make huge difference - some might be too slippery from the start, others too rough and brake the heads off. Regular PLA tends to work fine. Just few initial bends should be done carefully.This version is compatible with previous one - the heads and sockets share dimensions.Furthermore this model works rather well after scaling up in the slicer - which increases torque between head-sockets - opening them for new applications, STEP file included. They still will wore out after a while, but seem to hold longer than previous one. The best way to print multiple is to order them in triangles - where their custom brims overlap eacho
