KINGROON KP3S base with built-in PSU and tool storage box

Like many owners of this wonderful Kingrun KP3S 3D printer, I am tired of the PSU that took up extra space on my table. A quick search on Thingiverse gave me an option that I liked in almost every way. It is a really ergonomic and technical solution and I am very grateful to the author for developing this idea.

The main thing that I didn’t like was the location of the power button and the power cable socket on the left side of the base (But this decision has a reasonable justification, and it is not for nothing that the author included these elements only on the left). Since the printer already has a protruding space at the back (the stepper motor) it seemed logical to me to place the power interface on the same side right under the motor. It also seemed a good idea to organize a convenient and quickly accessible place for storing frequently used tools under the protruding part of the heated table.

So I took the original model from goodjung, mirrored it and slightly improved the concept. in particular:

• I changed the wall thickness, reducing the material consumption by 17%;
• Moved the power supply mounts to the left;
• Moved the hole for the power interface to the right side of the base;
• Modeled a tool storage box that fits perfectly into this design.

I like the final result - this is exactly what I wanted.
However, there are a few downsides that are worth considering for those who want to repeat this:

• moving the power module and cable socket to the right required extending the wires by about 5 cm (nothing complicated, but you should know about it in advance);
• the base itself, like in the original design, uses self-adhesive rubber feet from the printer, but for the storage box you have to use something else (for example, buy a set of rubber feet on AliExpress or, like me, use plumbing rubber pads that are ideal for this);
• you need fairly long (35 mm and longer) M3 screws - this came the original design and I didn't change anything here.

If you don't want to extend the wires or you don't need a box for storing small items, use the original design from the author - it will completely satisfy your needs.

Overall, I find the resulting design very functional and am grateful to the author of the original idea for the concept.
