Monster Kossel Mixed Frame

**UPDATE**: I've completed the Monster Kossel v1 and printed numerous hours on it, proving its reliability and precision. However, the v2 is underway, featuring acrylic panels for an enclosed printer with a HEPA filter and charcoal filter in aspiration mode to address health concerns associated with printing in multi-purpose spaces. These modified frame parts from the original Kossel frame work seamlessly with 2040 tower extrusions for increased size. The carriages are designed to snugly fit on 20mm sides when using OpenBuilds' v-roller wheels. Motor frames could benefit from an additional tweak for easier NEMA 17 stepper mounting, but this will be addressed in a future update. I've enhanced the bottom frame bits' height for increased rigidity between the tower and bottom frame. I'm still assembling this printer and have created a collection on Thingiverse for reference: http://www.thingiverse.com/goeland86/collections/monster-kossel - use these parts as a guide instead of searching for compatible components. **UPDATE**: I've realized that the carriages won't work with belts, so I'm including a thicker version to accommodate original Kossel Mini carriages. Axles have also been tightened for a snug fit on 20x40 extrusions. **IT PRINTS**: After weeks of effort, I finally achieved my first prints off the Monster Kossel's bed yesterday. I'm using a Replicape board with FSR bed leveling. Some users may notice that stepper lower screw holes are inaccessible; sorry about that, but holding motors in place with two screws is working fine for now. I plan on fixing this issue and improving cable management for those interested in mounting electronics on the top frame like I am. Final print volume is approximately 320mm diameter by 440mm vertically, meeting my expectations. Pictures will be posted soon after cleaning up the printer's mess. **UPDATE**: Despite using 20x40 extrusions, I still experienced annoying wobble on the frame, limiting print speed. To resolve this, I installed cross-bracing using 6.5 meters of 2mm steel wire, securing it with M5x5mm screws and tightening by hand to avoid warping the frame. This fix worked perfectly!
