{"data":{"model":{"id":"956448","slug":"alternative-buffer-for-prusa-mmu-system","name":"Alternative Buffer for Prusa MMU System","authorship":"remix","club":false,"excludeCommercialUsage":false,"price":null,"eduProject":null,"ratingAvg":"0E-10","myRating":null,"ratingCount":0,"description":"

The buffer has been designed to be mounted on the printer's enclosure, on which the filaments are placed and to guide the filament to the MMU. Nothing needs to be \"disassembled\" to load the filament. The buffer also takes up less space than the original. Mounting with the outlet facing upwards should also be possible but has not been tested.

To push the filament to the MMU, the slider at the front of the buffer must be inserted. After loading, it must be pulled out again completely so that the filament can be pushed upwards by the MMU. The feeding and buffering of PETG and PLA works without any problems. Very brittle or abrasive materials have not yet been tested.

Most materials such as screws (M3x6mm + M3 nuts), bearings, axles and collets can be used from the original buffer.

However, two bolts and nuts of the same size are also required for each buffer.

Because I have different collets, there is a buffer version for the Prusa collets and one for UM2 collets.

There are two holders designed to attach the buffer to 2020 and 3030 aluminum profiles. But with the three 8mm holes you can also design another holder and upload it as a remix ;-)

I have printed the buffer in PLA, but another material is also possible to reduce possible wear.
