Not the one I use the most, but still nice for many applications.
Cheap. Works. 'Nuff said.
This one's really useful if you want to get data in to a project, or want it really strongly attached.
My current go-to for power jacks on 5V applications. Snaps in cleanly and holds fairly well, unmistakably 5V USB power.
Sometimes you just need a little switch.
Heat inserts are a wonderful tool to cleanly bolt prints and components together.
You don't always want to use heat inserts. Sometimes you just want a tiny little screw. I use these frequently to keep light boxes together.
This is one of my favorite little secrets. Cut out the size you need an slap it on the bottom of your prints - now they won't slide around any more!
Rub-n-Buff is a metallic pigmented wax that makes some super cool finishes. Apply it thick or dry-brush it on, it'll make your prints pop!
CA glue is great for a lot of things, but E6000 is better. Keeps a little bit of flex and can bond dissimilar materials (like magnets to TPU). Just needs a little time to set.
I was happy to see so many people take my advice on using wire harness tape in place of electrical tape for their spools. Also extremely useful to add grip to PTFE tubing or hold down wires in prints!
