This really isn't an upgrade exclusive to the R2. But I'm really happy with it, so I decided to share. I made this leveling table out of 80/20 and some leveling feet I got from McMaster. I do need to stress that this table is NOT, in any sense of the word, cheap. This was extremely expensive, but I did over-engineer the hell out of it. You could probably make one out of 80/20 like this for about 2/3 the price; maybe less. A large chunk of the money was in the corner connectors (they have others) and you could probably use 5-hole flat plates instead of 7-hole. The table is 420 mm long, 420 mm wide, and 150 mm tall (without the leveling feet). The components used are as follows: 80/20 Parts (Part number is first): 40-4040-Lite: Extrusion - 340 mm long X 4 ($35.11) 40-4040-Lite: Extrusion - 150 mm long X 4 ($19.85) 33964: 90 Degree inside corner connector X 8 ($72) 40-4352: 7-Hole 90 degree angled squared flat plate X 4 ($34.80) 40-3203: 5/16-18 Standard slide-in T-nut X 32 ($25.28) McMaster: 6111K462 - Swivel leveling mount, plastic with cushion and 2" long 3/8-16 stud X 4 ($28.84) 91255A580 - 5/16-18 Button head hex drive screw, black-oxide alloy steel, 5/8" long, pack of 50 ($10.67) Total = $226.55 (OUCH!) Yes, very expensive but well worth it in my opinion. Not only will this last 1000 lifetimes, it's easy to add on to and build anything you can think of. As a matter of fact, I'm in the process of getting some storage bin hangers for it and adding a platform for a filament spool holder. I'll upload more photos when I get those mods done. The dimensions are a perfect fit for the R2, but I'll be honest, I wish I had made it at least 40 mm longer in length and width, just to be on the safe side. Maybe I will in the future. The large 7-hole flat plates are there mostly just so the rubber feet on the R2 have a platform. You can easily use something else, but all of the options I looked at were either right around the same price, or would be too time consuming to do. For instance, I was originally going to use a sheet of acrylic on the top instead of the flat plates, but I didn't want to have to face the sides of it on a mill; these flat plates look way better anyway (imo). You will have to drill and tap the holes for the leveling feet. If you don't have any taps, they will do it for you.............for a price (and a few extra days of in-house processing). Please know I'm not trying to brag, I just think this is an awesome upgrade that will last forever and can be modified to fit any situation. Plus, this thing is sexy as hell. If I could put this printer on a larger cabinet than it's already on (the black thing underneath), I would've made the leveling table much bigger. However, I'm already hurting for space as it is. Also, the reason I made it so tall (right now, with the leveling feet, it's 8" tall ) was so I could put (large) things underneath it, like the storage bin you see in the pictures. If you want to look at the components online, just type in the part numbers on the 80/20 and/or McMaster websites. The capacity of EACH leveling foot is 300 lbs. I highly recommend one of these if you feel like shelling out the $$$ for it. These corner connectors are ROCK-SOLID.
