Description
This is my first post in such a large community, and I won’t lie—it’s a bit intimidating 😅. Still, I decided to share this remix with some tweaks to the original design.
____________________________________________________________________________________________________________________________
White MMU:
This is a remix focused on making assembly easier. It includes models that correct small issues caused by material quality or the limitations of the machine used for printing, making assembly more straightforward.
For example: a hole to remove the door magnet if it was installed with the wrong polarity.
The parts in this model should be interchangeable with those from the original design.
Obviously, it’s up to each user to make the combinations they see fit, with the idea of improving the MMU and finding the version that best suits their preferences. For now, everything works using the original (stock) kit parts.
Current Version: W-MMX v1.0
(I slightly further optimized the microswitches on the body/gate areas.)
Printing suggestion:
Door spacers, right side panel, and cover.
______________________________________________________________________________________________________________________________
Corrected servo belt alignment in the 3D model and verified in a physical test.
Door dividers adjusted in height to prevent excessive play that could cause them to bind on the divider.
Body side panels adjusted:
Prevented door 3 from jamming by leveling the protruding camshaft bearing.
Reduced the gap on door 0 for aesthetic reasons.
Manual multicolor doors (approx. 6 layers):
Main door bodies for doors 0, 1, 2, and 3, plus a version with a 5 mm shaft.
Functional improvements on doors 0–3:
New internal microswitch position (~75% compression when installed).
If it doesn’t align correctly, remove the filament opposite to the ball and adjust slightly. There should still be enough material to use it as a press-fit like the original, if needed
(I recommend printing the stock body model with the microswitches, as it has been more widely tested by the community).
Small tabs for cable management; require 6× M3 inserts and 6× M3×6 mm screws.
Enlarged LED slot, more tolerant of less precise soldering.
Door number added to the rear of models that include a microswitch.
Longitudinal channel in the body for a possible microswitch PCB.
Holes compatible with EBB washers on the dividers.
Top hole added to all doors to make magnet removal easier if it was installed on the wrong side.
Doors without a number include a rear mark indicating their corresponding door number.
ECAS 04 and diffuser repositioning:
Flatter, cleaner aesthetics.
Complete front ECAS.
Rear ECAS without rubber.
Both body versions are included: the stock version and the short/new-style version.
LED diffusers also trimmed; two versions included, with and without numbers.
The clearance of the belt protector was slightly increased to avoid having to trim the cover, as happened to me due to a minimal difference.
