This unit is to replace some of the stock MMU3 buffer while using the new cassette system.
I have included a bracket to hang the buffer assembly from the back wall of the enclosure but it may not allow the proper clearances as I have not taken the time to work out any tube interferences. It is easy to change and update so let me know if you need something different.
Side Note: I made this as slim as I could be but it could be other wise one could just design the skirt portion to attach to the stock cassette holder.
Hardware List:
Bracket to Frame = At least M3x8, Qty. 3
Bracket to Frame = M3 Nuts, Qty. 3
Bracket to Buffer Assembly = M3x10 (or x8) SHCS, Qty. 4
Bracket to Buffer Assembly =M3 Square Nuts, Qty. 4
Cassette Holder to Upper Skirt = M3x12 (or x10) SHCS, Qty. 4
Upper Skirt to Lower Skirt = M3x8 SHCS, Qty. 4
Was hopping to submit it to a contest but I missed the enclosure one and don't feel like waiting until an MMU accessory one.
NOTE: There are 2 sizes of buffer wheels. Mine is for the larger on but there is one for the smaller wheels in the Remixes
Added Folders
09 SEP 2023 - Added 2 Lower skirt variants with mounting features.
17 NOV 2023 - Added Step files
01 JAN 2024 - Added files for modified lower skirt that moved the screw holes at the slightly higher. Added a 3 piece bracket for mounting the buffer to the printer frame in place of the PSU. the bottom hangs free but a screw in the bottom of the lower skirt can be used as a spacer (Yes , I'm feeling lazy here). I used 3 M3x12 screws to hold it together but M3x10 may be better.
