RMU-Mk3 Model Variations

The RMU-Mk3 filament buffer comes in two model variations. The Mod-S and Mod-T. 

The Mod-S is our original filament buffer designed exclusively for the Prusa i3 Mk3 printer with the Prusa MMU2 fitted. 

The design of the Mod-S was to allow for left side or under desk loading of filament from the spool. 

The Mod-T variant was designed to allow for easy top feeding. Our studies have shown that top feeding is more popular and the Mod-T is specifically designed to give simple yet reliable top feeding and management of the filament. 

When you buy the RMU-Mk3 Filament Buffer STL files  to print yourself, you will get the plans to print either model so you choose which one to use.

In the image above you can see the complete kit of parts that make the BF001 in the Mod-T variant. 

The right side pass through adaptors feed filament into the buffer while the left side feed out the Prusa MMU.
