Mendel Max 2 spool support and large dia. axle

thingiverse

Big diameter axle made for spools with a really big hole, ensures extra heavy duty supports reduce unwanted motion. Securely attaches to the very top of the Mendel Max 2 frame. This durable axle features an open center design that makes it print upright and sturdy even without bridging or support material when standing on end in the STL format. To prevent any mishaps, slow printing is highly recommended, especially during infill stages so the part doesn't collapse due to its unique hollow structure shaped like a cone at the top. A specialized filament guide has also been cleverly added to this robust design.
