IEC14 panel connector mount for Meanwell PSU

This is a very simple set of mounts to install an IEC14 panel connector on the very thin and flexible plastic cover of the Meanwell PSU (which comes, for example, on the Ender3Pro 3D printer). It is a sturdy support for the connector, and allows its installation in a space-lacking position. This is particularly useful if you want to only power up some small-powered auxiliary system when your printer is ON. For example, I use it for coolant pump and radiator fans, as I have three enclosed, liquid-cooled Ender 3 Pro printers. AND, I love IEC13/14 connectors!

DISCLAIMER: THIS PROCEDURE INVOLVES MAKING CABLING AND CONNECTIONS AT 230 V. THIS VOLTAGE CAN KILL AND REQUIRES CAUTION AND TOTAL AWARENESS OF WHAT YOU'RE DOING. IF NOT SURE, LET SOMEONE ELSE HELP YOU. WE ARE NOT RESPONSIBLE FOR ANY KIND OF DAMAGE TO PEOPLE OR THINGS.

What do you need?
- this STLs and a 3D printer
- IEC14 panel connector with two screw holes, as in picture
- 2x M3x22 hex socket screws
- 2x M3 nylon insert lock nuts
- 3x pieces of 1.5 mm^2 section, 7-10 cm long electrical wire
- 3x 4 mm diameter eyelet insulated faston
- 3x 3 cm heat-shrinking tube (to insulate the soldered posts on the back of the IEC14)

How to install it? Easy!
- Disconnect the PSU from the grid and the printer. Remove the 3 hex screws holding the black plastic cover on the PSU.
- Hold the outer mount firmly on the plastic cover, right to the side of the IEC13 panel connector.
- Drill two 3 mm holes on the cover, using the holes of the mount as guide.
- Use two M3 x 22 hex screws and two nylon insert lock nuts to secure the outer mount and inner mount to the plastic cover. Try to get everything nice and square.
- Using a drill and/or a Dremel/clone rotary tool, make a hole in the cover, using the mounts as templates. This hole will now have the same shape of the IEC14 connector.
- Unscrew both screws, use a soldering iron and the fastons to make secure and properly insulated connections.
- Assemble the connector on the panel, using the 3D printed mounts.
- Connect the IEC14 to the PSU. You only need the three right-hand side posts: ground, Neutral, Live. Be careful to connect everything properly. Double-check all connections. You can wire two fastons to the posts, putting them "back to back" on their (mostly) flat side.
- Try to squeeze all the old and new wiring inside the cover, re-install the original three hex socket screws and...have fun 3D printing!

It's not safe to pull a lot of power from your new connector, as all of it will travel through the small red switch of the PSU. As a rule of thumb, I will not go over 50 W. Small pumps and fans are OK. Additional heaters are NOT OK, just to give you an idea.
