SMD soldering clamp
thingiverse
Simple structure that help soldering SMD components. The general idea taken from https://www.thingiverse.com/thing:2772207 The design has been simplified, enforced, and adapted for 8x20mm spring(typical spring used in extruders). Extra parts: - Spring 8x20mm - 15mm M3 or M4 screw/nut - 20mm long metal rod (e.g. part of bike spoke or m2 screw without cap) Assembly tips: The simplest way to connect metal end is to heat it up with soldering iron and stick it into the plastic. Use m3 screw for arm/base connection for lesser tension.
