This happens to be a design from scratch model i made as a gifting idea for my nephews.
Mom wanted a package topper for her grandkids as her packaging was in the shape of a snowman so i designed this tophat to go on its head.
was playing with my MMU2.0 unit for my Prusa i3 mk3 and designed this unit as 4 different bodies in Fusion 360 and sliced with Slic3er Prusa Edition.
Printed with mostly default settings, only changing the infill, and extruder number per body.
So far have printed 2 of these, 1 with white band, 1 with red band.
Printed without supports @ .2mm layer height
Prints are mostly hollow with 10% infill
Print time took about 12 hours for each give or take a few.
used black for brim of hat and stack as extruder 1
used silver for buckle as extruder 4
used red and white as extruder number 2
all these settings can be changed in Slic3erPE to match what colors you want to use.
While i did print these hats without supports for the buckle there was some drooping in the lower part of the buckle so if you want to see how well supports will work, id recommend using one of the (as of now) newer features of Slic3erPE, the customized support enforcer at the middle buckle level.
I also recommend that the seam alignment be put to rear.
Aside from whats listed above, change settings to match what you want and have fun with this.
Like what you see? Feel free to leave a tip!
To print this model using Slic3r PE, load any one of the parts onto platter. Then right click onto the part on the platter to access the pop up menu and go to settings. using the add part button in the new window, select the rest of the parts of the model and click ok.
now all the parts should be loaded into proper orientation and you can then select from the various options in the new window to assign extruder numbers to the parts, add custom support if you want amongst other options.
MMU printing is a slow process but id recommend at least that for a finer detail i would prob use a .15 layer height before trying a support on the model surface for the bucket overhang.
aside that, adjust the infill to give the least amount of material but the best support for the surfaces. ive gotten it down to 10% infill so far, one uses rectilinear, another one used cubic. In this model I would recommend rectlinear as there is a lot of retraction going up the sides of the model using cubic infill, that could lead to a clog and stringing, although the stringing wouldnt be visible from the outside.
used the stock Slic3er Prusa Edition, MK3 MMU, .2 Generic PLA profile with small changes to infill and perimeters (white model uses 3, red uses 2, made no difference)
