Bear Upgrade Prusa MMU2 Horizontal Mounting Brackets

thingiverse

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.
