Description
This is a filament box with an auto-rewind mechanism, designed as a compact and functional replacement for the original MMU3 buffer.
The box includes:
A slot for a silica gel box
A dedicated space for a thermometer/hygrometer
New custom supports specifically designed to adapt the auto-rewind system to this box
A custom filament guide bar, optimized for filament alignment
A drill marking support to easily mark the screw holes for fixing the supports inside the box
I slightly modified the container by removing the original internal structures to fit the Vincent Groenhuis auto-rewind system.
The box itself is available at low cost on Temu or AliExpress – I will include a link in the description: https://it.aliexpress.com/item/1005007783900995.html?spm=a2g0o.order_list.order_list_main.5.54373696aokIWV&gatewayAdapt=glo2ita
The lid of the silica box must be printed with top and bottom horizontal layers set to zero
