Feet for Wanhao Duplicator 6 (WD6) Monoprice Ultimate

thingiverse

So I purchased two Monoprice Ultimate 3D printers, which are actually rebranded Wanhao Duplicator 6 models, and one of them experienced an issue with the Z-axis. It turned out that it didn't turn smoothly enough for the stock stepper motor to not skip steps, so I obtained a larger stepper motor that extends downwards, thus requiring some clearance. This led me to create new feet for the WD6. Honestly, the printer really needs these in any case as it could benefit from additional space for better airflow (especially if you have it on the floor like I do), and the stock feet are subpar and won't stay attached. For something as simple as a foot, there are quite a few design features: - They are press-fit. - There are two pressure nubs at the top of the channel to secure tightly. - At the bottom of the channel it squares off to mechanically lock the edge surface into place. - The internal geometries all have rounded transitions in order to improve force distribution and prevent stress fractures. - They incorporate a corner design for several reasons: 1. It stabilizes the machine, as the corners represent the absolute furthest possible mounting points in both the X and Y axes. 2. It enables more surface area for better load-bearing capacity. 3. The opposing angles of the two adjacent walls help to lock and stabilize the foot against all force vectors, preventing shifting and movement, rotation, and keeping the foot on the printer securely. - The part is oriented to print at an angle that will provide maximum strength (since we're not applying force against layer interfaces). - The ends are rounded in order to protect surfaces it may sit on.
