I am not sure how well this build will go in the real world but in the end you will still need 3 printed parts (the hot end holder and two belt holders due to the way things do not line up) and I haven't touched my piece of junk printer since May (too many odd issues) but I think I could squeeze out something enough to get on this build and make the parts better. Now when it is all said and done the bed only moves in Z (YAY, no more banding and taller prints are doable) and all wheels + vslot design. I tried to make it so you would not have to cut anything, or print anything, but alas you will have to cut 540mm * 2 and 410mm * 4 out of 3 1m long 20x20 plus print those 3 items I mentioned. Question I now have is I may be trying to over engineer this because my i3 rework was an absolute nightmare of a printer and I was tired of having to dial it in and spending 1k+ hours on it to dial it in to print ALMOST 1kg's worth of parts. No joy. My final mechanical parts price came to $548.18 Plus s&h which made my jaw drop and made me wonder about the above I mentioned. Lets say I have an L in 3 dimensions (a corner of a box) would I need 3 90 Degree Joining Plates in each corner to make it not wobble and be very stable/rigid or instead would 3 Cast Corner Brackets achieve the same level of rigidity/stablity ? My current design has both in all corners and I was wondering if both are needed or would one, and which one, would be enough? edit: Here is a picture of what I am talking about of one of the corners.
