Rev E builds on the previous Lemontrons with the Endgame Lemonstruder, the final complete extrusion system with a 4.5: 1 gear reduction + 100% PTFE filament path, a relocated tensioner unlocking extra rigidity, quad fans that are also bigger, a wraparound tool head, and hundreds of other tiny tweaks improving fitment, further shaving the BOM, and increased rigidity throughout.
Printing difficulty: Level 10
This bad boy requires a recent enclosed printer or tuning that’s considered perfection-seeking! These tolerances are tight and print quality must be off-the-charts high. As for the actual assembly, the difficulty is much more forgiving– the tools are common and the build process is extremely rewarding.
Required Tools
Screw Drivers
As for screws, only M3 (2mm Hex Bit) and a few M2.5 are used. I recommend having a dedicated high quality 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.
