Reptar XY!

After fine-tuning and modifying some of MoonCactus' outstanding XY blocks, I discovered that although the design was phenomenal functionally, it was about equally as demanding to assemble as the stock UM XY blocks. So while striving to preserve the major benefits of the original (integrated adjustability, low profile, removable without taking out the 8mm axes), I set out to redesign them - with improved assembly and accessibility in mind. The result is the Reptar XY block, a robust, easy-to-print, simple to assemble, highly functional XY bushing block... which was designed almost entirely before I printed it in purple and green and welcomed the fact that it resembled a dinosaur. Anyway, as I mentioned earlier, it offers some significant usability improvements: - The Main body (green part) snap-fits onto the bronze bushing and the 6mm rod, holding them captive - which means you can assemble most of it without any screwing, and then add screws later to make everything secure. - All of the screws are accessible from the front side, including the tension adjustment screw. This is a very nice feature and makes assembly much more enjoyable. - The bronze bushing does not get deformed as you tighten things up. - The limit switch 'spikes' are a separate part, which means you print 4 of the same assemblies and just screw the 2 limit spikes to the appropriate XY blocks - fewer files to manage. **2013.08.20 - v1.16 Update:** I've uploaded the latest STL files, after printing several dozen of these and installing them on 3 machines. Now I believe that a combined XY block + tensioning mechanism is not necessarily the best path forward (see comments) and will be redesigning this to simplify it further. **2013.08.06 - v1.16 Changelog:** Added small tabs to locate the bushings! **2013.07.31 - v1.15 Changelog:** Changed the shape of the clamp jaw to get better clamping and a cleaner print. Parametric files only at the moment, I'll upload STLs when I get a little more testing in. **2013.07.30 - v1.14 Changelog:** Updated switch trigger clearance. There will now need to be two separate parts for this, unfortunately. Uploading the longer one soon. Made some improvements to the tensioning mechanism as well as the clamping. Parametric files only at the moment, I'll upload STLs when I get a little more testing in.
