I have a TS100 soldering iron. I was very pleased about this iron since it is programmable and overall lightweight. However, most standard soldering iron holders are not capable of holding this iron due to the small form factor.
After looking at some other options on Thingiverse, I found prints that either require specific washers, rollers, or peculiar parts. Also, many of those designs involved more filament consumption or assembly than I wanted. In an attempt to make something more optimized and minimalist, I designed my own which can be mounted on a table. This design uses only 8 grams of filament.
Basically, there is only one part to print. Bend a paperclip and you have achieved an elegant yet low-filament soldering holder for the TS100.
After printing this part, take a standard paperclip and unbend the primary fold. Then bend the sides of the paperclip downwards to create an "M" shape. Cut off the excess parts and insert into the front base. Adjust height as needed.
