I liked the design that McCarter14777 used, but I needed the riser to be a bit taller. This should raise the IKEA Lack legs 101.5mm or so off the surface it's on. This was enough to give my Monoprice Maker Select (Wanhao i3 v2.1 clone) enough room, even with my raised z Axis mod.

I printed this with eSUN ABS+. I printed it at 0.3mm at 80mm/sec. Probably would have been better if I slowed that down. I did have to use a temporary cardboard box to keep the part from delaminating. I'd have used a better enclosure, but if you're like me, you're printing this part out to build yourself a legit enclosure. That wouldn't be a problem with PLA or PETG.

The main thing that I did that was different than most other people, is I made all of my panels magnetic. I glued high strength magnets to the red brackets in all 4 corners. Then I glued washers on to the plexi. This means that I can easily snap my plexi in to place and remove it whenever I want. This makes access really easy. The front panel just has two handles screwed into the plexi. To remove it, you just pull the plexi out and set it on the ground. Sure, I could have done something with hinges, but this works perfectly as is. I've been using it for over a year no complaints.
