D-bot stepper mounts with zip tie slots

thingiverse

The custom-made PETG-printed mount plates for my D-bot's stepper motor mounts were prone to flexing a bit when the steppers were under belt tension, causing the drive shafts not to stay perfectly vertical anymore. Although it wasn't a major issue, even a slight angle in the stepper drive shaft toward the printer could lead to the belt bunching up on one end of the drive pulley. I redesigned this using Tinkercad by adding two slots to the left side mount and one slot to the right side mount, allowing for a large zip tie or ties to secure the motor firmly to the mount, preventing it from leaning over under belt tension. The reason for the different number of slots between the two was purely practical - the mounts and screw hole locations aren't identical on both sides, so two slots fit on the left and only one slot fits on the right. A single slot should be sufficient to allow the zip ties to bear some of the torque from the X/Y drive belts, keeping the stepper shafts perfectly vertical. Print this using the same method as the original D-bot stepper mounts. I printed mine in PETG with 100% infill at 260 C/70 C on my D-bot, printing at a speed of 50mm/s.
