I've recently started using SMD components, as cheap, professional quality PCS's are now readily available. I personally use easyEDA, with it's free on-line Schematic & PCB design tools & low cost PCB manufacture.
I found soldering easy my normal iron & a tiny tip, but De-Soldering is quite difficult for small resistors & caps, as both sides need to be heated at once, and the hot-air rework tool just gets nearby components too hot IMHO.
I searched Thingiverse & found minipimmer's "3D-printed SMD soldering tweezers" https://www.thingiverse.com/thing:1934731 but found the soldering irons kept falling out.
SO - here is my version, that has worked OK on unsoldering a few SMD resistors & caps, plus it's very easy to remove an iron for single soldering iron jobs - I like using these instead of my temperature controlled Hakko, as these $7 USB irons heat up many times faster (no very useful for big soldering jobs, of course)
I have included my scad source code, so you can modify it for different printers or irons
