Squash Ball MK4/MK3s/MK3s+ Vibration Damper V4.0

New version, more improvements (for some pictures scroll down):

• 100% print in place, NO SUPPORTS!!;
• Easier to print dovetails - more area to grab on the build plate!;
• Zip ties no longer optional nor required;
• Better tolerances - Easier to print for all;
• Click in place mechanism - Prevent balls to fall, but still making it easy to remove;
• Lightning Fast: 31% faster than V3 (4h30min vs 6h36min); 43% faster tan V1 (4h30min vs 7h55min)
• Feather light: 37% lighter than V3 (41g vs 66g); 49% lighter than V1 (41g vs 81g);
• New symmetrical holder as option;

Comparison (printing in MK3s):

Mk3s+ speeds and 4 squash balls supports

Print Settings:

Off course you need squash balls for this, i recommend double yellow dots as they have the best absorption:

(we need absorption, not bounciness!)

Use minimum 4, recommend 6 (should be more than enough for printers that do not have filament spools in the frame, for example, inside a Prusa enclosure), or all-in like my current setup 8.

Default PETG 0,2 with the following modifications:

• 3 Perimeters;
• 5 Top Layers
• 5 Bottom Layers;
• Ensure vertical shell thickness - OFF.

If you don't have printer OCD like me ( :P ), you might need to use brim for the dovetails.

Like previous model, a tiny bit of lubricant helps everything to be easier!

The model is designed to be printed in only one way without supports, it will fail if oriented wrong, please see picture below:
