Double-Ended MC4 Solar Connector Tool – Release and Tightening Spanner

This practical 3D-printed tool is designed specifically for working with standard MC4 solar panel connectors. It's double-ended for maximum versatility:

One end: Features two prongs to safely release/unlock locked MC4 connectors by compressing the side clips, making it easy to disconnect mated pairs without damaging them (perfect for maintenance, reconfiguration, or troubleshooting solar arrays).
Other end: Open-ended spanner/wrench for tightening or loosening the cable gland (cap nut) on MC4 connectors during assembly.

Compact, lightweight, and ergonomic, this tool saves time and frustration compared to using fingers or improvised methods. It's an essential accessory for DIY solar installations, balcony power plants, off-grid setups, or professional PV work.

Recommended Print Settings:

Material: PETG or ABS for durability and outdoor/UV resistance (PLA works for light use but may be less robust).
Infill: 50-100% for strength.
Layer height: 0.2mm or finer.
No supports needed (depending on orientation).

Print one or two – many users print pairs for easier assembly! Great for anyone building or maintaining solar panel systems. Happy printing and safe solar setup! ☀️
