Ultimaker Original Feet with Silicone Dampener
thingiverse
I engineered a novel foot for the Ultimaker Original, which features a hollow foundation designed to pour two-component silicone into it. Following the print cycle, rotate the component upside down and combine about 18 milliliters of silicone before filling the cavity to its highest point. As soon as the silicone is fully cured, use a sharp blade to detach it from the surrounding walls and carefully remove the frame. Three openings are precisely positioned throughout so they grasp the silicone firmly. The type of silicone I use is consistently very pliable and can lead to print head movement due to weight shifting issues if too soft. As a precautionary measure, using standard retail silicon should suffice. The Ultimaker's feet adhere strongly to the printer surface such that lifting without it toppling over becomes straightforward. This design feature was incorporated on purpose, as an elevated platform with PC fans integrated within is next on my list of creations. The plate will rest upon a wooden slab about 2 centimeters in thickness once attached. When doing so, two powerful fans installed will work to eliminate heat and make removal of the cooling unit unnecessary. For these new feet, I used Innofil3D White PLA at a speed of 80 millimeters per second, combined with layer thickness set at 0.2 millimeters and wall thickness measured at 0.8 millimeters, accompanied by fifty percent infill to guarantee durability. A bed temperature of sixty degrees Celsius achieved ideal results while printing directly onto Kapton tape with minimal application of ABS-acetone solution for easier adhesion. When testing these components with personal force, one surprisingly held strong against intentional crushing; possibly only an entity as incredibly robust and imposing as Chuck Norris could have succeeded in breaking it apart. Therefore, duplicate both of these new foot designs for side-to-side mirror orientation on your printer using Cura. Once the models are uploaded to the program interface and viewed upon the virtual build platform click "mirror" located at the bottom menu bar before then proceeding with mirrored adjustments based either on the x or y axis. During print processing adhere these two identical structures placed upright such that hollow bases reside toward downwards positions on top table level with necessary printed support structures positioned for adequate holding power against gravitational downward force which would pull foot back against bed otherwise compromising print finish quality when silicone molding adheres poorly over less-smooth bottom surfaces areas as can sometimes be the case when lower surface has less than desirable or optimal finish
