Flexible Helping Hands Base

thingiverse

I'm using these helping hands for my soldering projects: https://www.amazon.co.uk/gp/product/B078PLRBHW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. The attachment system is flimsy and moves easily out of place, which led me to create a bespoke solution with a heavy base for added stability. The base will work with any helping hands or other devices featuring M4 holes in the corners of a 32.4 x 24.4 mm rectangle. To build this base, you'll need four M4x20mm screws, four M4 nuts, and 100 two-pence coins (or objects up to 26mm in diameter). I chose two-pence coins because they are heavy and readily available; 100 pieces weigh approximately 700-750 grams. Combined with the helping hands' weight of around 100 grams, this base should hold securely. For users with different coin sizes, a "blank" bottom piece is included. Simply load it into your preferred CAD software and add custom cutouts for your chosen coins. Some ideas to consider include adding non-slip material to the base's underside or creating custom holders, nooks, and crevices on top to enhance soldering (or other) work.
