Bear Upgrade Prusa MMU2 Horizontal Mounting Brackets

This is a Bear Upgrade friendly version of the same horizontal brackets I designed for the Multimaterial Upgrade 2. I designed these in Tinkercad so no source files are available. I haven't had a chance to print these out as I haven't completed my bear upgrade yet so excuse the lack of pictures. I will get some up when I print them out.

The MMU2 is not particularly Lack Enclosure friendly due to the added height and mounting angle using the provided brackets. The angled mount is necessary to maintain the 210mm printable Z Height but if you are willing to lose a few mm of Z height you can mount it perfectly horizontally. Realistically I rarely go past 180mm Z height so I use the lowest mount possible. An added benefit is significantly reduced friction for incoming filament from above the MMU unit.

There's 2 versions available in both the Snap design by KostaMi and Bolt design by pekcitron.

• 195mm Z Height version - This one allows enough access to troubleshoot the MMU unit as the angled bracket in an extended Lack enclosure.
• 180mm Z Height version - This is the mount I use, it is as low as the frame will allow the unit to be mounted. It gives great access to the MMU unit for troubleshooting and reduces the incoming filament friction a lot.
