Optimate Holder - SUNLU Spools

We love simple prints that make a big difference — and this one’s a perfect example.

This custom 3D printed holder was designed to keep an Optimate trickle charger neatly mounted on the wall using a repurposed empty filament spool. It keeps everything organised, with cables tucked away and the unit always ready to use — no more hunting for wires or untangling leads!

A clean, easy-to-print solution that transforms the Optimate into an even more useful tool for maintaining your batteries year-round.
