Prusa / Ikea Lack Enclosure PSU Wire Length Solution for i3 MK3

thingiverse

Human: I'm a huge fan of the Prusa / Ikea Lack enclosure design. But after assembling my Original Prusa i3 MK3, I discovered that the wires running from the PSU to the printer were too short for optimal use. In my case, this was definitely the case.\r\n\r\nI noticed that the wires emerged from the "rear" of the PSU and then had to loop back around to the "front" (the side with the power switch). This made me realize we could gain a couple of inches of usable length if the wires simply exited from the front. So I created a modified version of the original PSU cover, relocating the cable hole to the front and increasing its height by 8.5mm.\r\n\r\nTo minimize the travel path of the wires even further, I modified the bottom corner of the enclosure, moving the passthrough from outside in. This works with the existing mating cone after rotating it 180 degrees.\r\n\r\nNote that due to the increased height of the PSU, the bottom PSU holder will need to be lowered slightly.\r\n\r\nOverall, this is a pretty straightforward swap. My only advice is to exercise caution not to tug too hard on things when swapping out the PSU housing. To give the power entry connector enough mobility to extend over the new housing and into its slot, I cut the zip tie that was providing strain relief to the black and white cable. If you need to do this as well, just be sure to replace it with a new ziptie when finished.\r\n\r\nLastly, I printed everything without supports. There is one 90deg overhang on the PSU housing that had some sagging, but it looks like the original Prusa part had this too and it didn't/doesn't affect fit.\r\n\r\nI hope this helps solve the wire length issue and allows more people to enjoy what really is an excellently designed enclosure!
