Kossel 2020 mains inlet and electronics front panel

This is the front panel I use on my 2020 Kossel for mounting the mains inlet connector, fuse, on/off switch, and the Duet electronics. It includes access holes for the Reset and Erase buttons of the Duet 0.8.5 or the new Duet WiFi board, along with a thin section for the LEDs on those versions of the Duet to shine through. It can also be used with a Duet 0.6 board. Pick the version with WiFi or the version with Ethernet depending on which Duet you have.Please note, this version does not fit the Duet Ethernet because the cutout for the Ethernet connector needs to be moved.

A matching rear panel at http://www.thingiverse.com/thing:1617834 supports the back of the board and a 40mm fan for cooling the stepper driver chips in the confined space under the bed. See my blog at https://miscsolutions.wordpress.com for detailed instructions.

Instructions

The mains inlet parts that this design accommodates are:

• Bulgin PX0575/15/63 low profile snap fit IEC mains inlet (Farnell 469658)
• Panel mounting 20mm fuse holder (Farnell 9630198)
• Arcoelectric H8553VBNAO illuminated mains switch (Farnell 150388)

The panel is a little too thick for the locking tabs of the Bulgin snap-in mains inlet to engage fully, so I used a small file to chamfer the top and bottom edges of the back of the hole until the tabs would lock in place.

You can get other IEC mains inlets that integrate the switch and the fuse, but I didn't find one that was slim enough to fit in 20mm height.

Before fitting the Duet, check that the Reset and Erase buttons sit properly in the holes provided for them, because if the panel fouls them then you might accidentally erase the firmware and need to re-flash it.
