The X2D is a dual-head printer, with the main and secondary nozzles switched via a nozzle switching lever. However, there are large gaps at both ends of the lever, allowing printing debris to easily fall into them, making it impossible to remove and even jamming the movement mechanism.

To effectively solve this problem, I designed this special accessory. Its innovative 0.12mm thick "thin brush" structure perfectly balances preventing debris from falling out while not affecting the lever's movement direction. I highly recommend equipping your X2D with one 👀

There are several issues with this model, both in the design and the print preset. I'll list the design issues here, and the preset issues in a reply (due to comment length limits). Design issue 1: the retaining tabs are too tight at 2.0 mm spacing (identical to the actual dimensions of the pin on the printer). Adding 0.2 mm here (and to the latching hooks at the top) fixes that; for anyone wishing to print the current version: add a negative volume of type "rounded rectangle", scale it to X=2.20 x Y=2.60 x Z=2.30, and move it to object coordinates X=0 / Y=8.25 / Z=0.85. Then file off the latching hooks a tiny bit on the inside after printing. Design issue 2: the width of the brushes is not optimal for good adhesion between perimeters. More details in a reply, but as a quick fix, set wall generation to Arachne, and Elephant Foot Compensation to 0.07. Design issue 3 (minor): the tabs would be less likely to break off with a slightly larger fillet (and/or a fillet on the inside).

@Wmbrt

Preset issue 1: it really should be printed in PETG - less brittle than PLA, allowing the little brushes to flex without breaking. Preset issue 2: without a higher value for the infill, the "platform" for the two tabs is prone to shearing off the base. For such a small model, 100% Rectilinear infill has a negligible impact on print time and filament use. Preset issue 3: this model really needs Arachne wall generation. With that enabled, the slicer will create continuous loops from the cover "frame" to the brushes and back, making them significantly less likely to break off over time. A Concentric bottom surface pattern further improves the first layer. More details in the next reply. Preset issue 4: painted seams on the outside of the tabs improves the dimensional accuracy of their spacing (otherwise the slicer will create the seams on the inside), even with scarf seams. In addition, a seam on one of the brushes can be prevented by painting one on the opposite side of the "hole".

@Wmbrt

Regarding Arachne wall generation and the sizing of the brushes: there is an optimal wall thickness for FDM printers, calculated using the following formula: OptimalWallThickness(NumPerimeters, OuterWallExtrusionWidth, InnerWallExtrusionWidth, LayerHeight) = # the two outer walls 2 * OuterWallExtrusionWidth # subtract one count of overlap between the two outer walls - LayerHeight * ( 1 - PI / 4 ) # for any remaining inner walls, add the extrusion width minus overlap to adjacent perimeter + ( NumPerimeters - 2 ) * ( InnerWallExtrusionWidth - LayerHeight * ( 1 - PI / 4 ) ) In this case, for OuterWallExtrusionWidth=0.42, InnerWallExtrusionWidth=0.45, LayerHeight=0.12, NumPerimeters=4, it needs a modeled brush width of 1.66 mm, HOWEVER, Elephant Foot Compensation needs to be factored in, so we need to add 2*0.15 for a total of 1.96 mm. Or keep the 1.8 mm width and set Elephant Foot Compensation to 0.07 in the profile. With all that applied, it prints and fits perfectly!

Uploaded a (PETG) print profile with fixed tab spacing, solid infill, optimized walls, and clean seams. Still needs the latching hooks at the top of the tabs to be filed down ever so slightly before installation as noted in the description.

had to trim slightly to fit in with other crack protectors in place, but got it in so it does is job!

X2D, it doesn't lock and remains wobbly

It just won't hold, I can't push it onto the front nose and it always springs off by itself, I even printed it in TPU. even here it springs off by itself again

Try my fixed print profile!

Great to hear! Don't forget to rate that print profile so others know which one to pick :)

PETG w/ fixed tab spacing / layer adhesion / brush strength

Thanks for all the corrections. This fits well - not around the dust cover I already had in place, but that's no fault of this model. It's held in place firmly and provides a lot of protection. The brush configuration is ideal, not too stiff. It doesn't impede the ability to change nozzles at all. Printed in Bambu Lab PETG Basic black. Thank you!

PETG w/ fixed tab spacing / layer adhesion / brush strength

I only gave this 4 stars, not because the design is not good, but because I was unable to get it to fit and stay on . I printed both the PLA and PETG versions, both in PETG since the X2D chamber gets hot, and neither would stay on. Excellent idea and very nice design though. And before anyone comments, yes my printer is calibrated, both the full calibration and the vision encoder calibration, and my filament profile is also calibrated. Print accuracy is not an issue as I have printed high precision functional designs that are perfect fit, part into part :-)

@Wmbrt

Can you provide some details on what the fitment issue was with the "PETG w/ fixed tab spacing" profile? Are the tabs still too tight to fit around the pin? Can you use calipers to measure the printed model's tab spacing, and the actual width of the pin on your printer?

Thank you for this cover. Simple, but helps prevent debris from getting inside these spots.

Cool !!
