Simple Heatset Press for TS101/Pinecil

I've found the Pinecil soldering iron fantastic for inserting heatset inserts, but it can be tricky to get them level by eye alone. There are already some excellent designs for dedicated arbor presses here on Printables, but I found most of them to be a bit over-engineered, especially when they call for precision ground linear rails and bearings.

Instead of that I went for maximum simplicity - all that's really needed is a bubble level. So, this is just a bracket to attach a bubble level to a Pinecil iron, making use of the grounding point screw. There's a small version that uses a 15x8mm bubble level (widely available on Aliexpress), which I've found small enough to leave attached when I'm soldering, and then a large version that uses a 32x7mm bubble level. These should also work on the TS101 soldering iron, but I've only checked the Pinecil
