I have 3D printed many different holders for Milwaukee battery and tool holders to help organize your tools.
M12 & M18 Battery holders are $5 each
M12 tool holsters are $25 each
M18 tool holder $5 each
M12 tool holders $10 each
Multiple Battery caddy $65
I can make them in custom colours and materials if desired for additional costs.
I can make other brand holders aswell but I personally only use Milwaukee tools so fitment maybe an issue so I would suggest bringing your tool or battery to test first if you require a different brand.
I also have the plans to make multiple battery holders for construction job sites as well as charger mounts and holders.
If interested let me know.
