The following tools are strongly recommended!
Screw Drivers
As for screws, only M3 (2mm Hex Bit) and a few M2.5 are used. I recommend having a dedicated high quality Wera 2mm hex screwdriver, plus a bit for your drill.
3D Printing Tools
You will need a modern, enclosed 3D printer to print the Lemontron parts. Razors for scraping. A craft knife for tidying blemishes. Supa glue for the Lemonstruder parts (the “liquid” one not the thick one).
Electrical Tools
A soldering iron is needed for soldering the edge connector and other wires. For the motors, you’ll need some wire cutters and a crimper. You may try your luck with a soldering iron.
Trimming Tools
The motor shafts and X-Axis rail must be shortened. A Dremel with a cutoff wheel is recommended. Flush cutters are also required, but 3d printers tend to come with those.
