BigPrinter Customization

thingiverse

Some months ago, I realized my Prusa I3 clone was consistently too small. I had to cut my models in half multiple times just to get them printed. So, I decided to build a BigPrinter clone. This project utilizes 20x20 aluminum profiles which are screwed together with previously printed brackets. All the parts are easily accessible and can be customized to your personal needs. Ivan kindly offered a link to his Fusion360 project on his former website files, but it seems he hasn't updated anything in the last months or is secretly working on some changes. So, I decided to publish my changes and improvements so far. Publishing all the files for other people's use will take some time, though. Since it's a rather long list, I included photos of the relevant items. All items belonging together have the same name prefix. I also found another project here on Thingiverse which was customized to a size of 300x300mm and 500mm height. Some of the parts are included in my files. Some of the files like the original cable chain came from Thingiverse, while the Raspberry holder was a contribution on Ivan's pages. Unfortunately, I've lost all the original URLs. The original measurements don't give the mentioned 300x300x600, which is just the inner size. Quite some size is lost due to necessary mechanics. For a rough overview: currently, I have a printable space of X:320 Y:530 Z:260. The profiles and rods have the following lengths: X rod: 48.5 profile: 44 (the difference must be the same as in the original parts list) Y: rod: 710 profile 702 (profiles could be 30mm longer for the same rod) Z: rod/profile: 350 The short vertical profiles for the middle carrier profile is 170 but could be anything you need.
