Layerfused X-series Wide Feet

These feet were inspired by 247printing's wider feet for the Voron V0 to improve stability. These mounts move the feet outside the edge of the motion system of the printer, which should improve stability when printing at high speeds. I found that between the relatively narrow base of the X301 (compared to its motion system) and the storage unit it was sitting on, the printer would tend to lever the entire stack back and forth when moving at high speeds, so this is an attempt to address one of those issues.

The front foot mount is a single model because it's symmetrical. There are different right/left parts for the rear, though they are just mirrors so you can use a single model and mirror it in the slicer instead as needed. All holes are sized for M5 hardware. I used common 38 mm rubber compressor feet for my installation, available at online retailers.

Due to limited space in the rear (depending on the rear panel design used), the stock rear foot design is meant to use M5 holes tapped into the 2080 extrusions for a more secure hold. For those without a tap on hand, there is a version that has M4 holes which should allow steel M4 screws to cut their own shallower path through the soft aluminum, though they might be a bit loose. 

Printing tips

As these will be load bearing parts, it is best to print them with a higher number of layers and ideally out of a creep-resistant filament like ABS. I did 5 perimeters with 10 bottom layers for good measure, though I only had normal PETG on hand.

There is a 38 mm printable foot model also included. This can be printed out of flex filament or solid filament depending on your noise requirements. I have not printed this model out to test yet so I cannot presently recommend any specific settings.
