Calipers are essential not only for calibrating your 3D printer but also for taking accurate measurements when designing your own 3D parts. We’ve included our favorite set of digital calipers below. These calipers provide excellent quality and precision, and with their fully stainless steel construction, they are made to last. Check out our Amazon Affiliate link listed below.

PINECIL – Smart Mini Portable Soldering Iron, Small
I've used every soldering option available, from cheap dollar-store soldering irons to expensive, bulky soldering stations. Never before have I loved a soldering iron as much as I love the Pinecil64. This soldering iron, with its built-in digital display, runs off USB Type-C, which works perfectly with my 65W dual USB laptop charger. The tip system makes this soldering iron even better, as entire ends can be hot-swapped instantly, including tips of all types, such as those for heat-set inserts.
