Bowdenhotend holder for Prusa i3 x-carriage

pinshape

Another fun thing coming out of messing around with DSM (http://www.rs-online.com/designspark/electronics/us/page/mechanical) is indeed falling in love with this application for 3d printing. The carrier fits the standard length x-carriage of Prusa i3 (https://github.com/josefprusa/Prusa3), which I did not design myself. Huge credit goes to Joseph Prusa, well known in RepRap community, for his great work on Prusa i3 parts. These two parts are designed airtight. If you experience issues with fit-in-place parts, consider using XY-compensation option of Slic3r or setting up fake bigger nozzle diameter in your slicer (or simply file down the parts slightly). It holds two cheap 8-dollar Chinahotends firmly and also carries 2 fans. One is a 22mm fan for hotend cooling and the other is a 65mm CPU cooler for print cooling. Sliced well with CraftWare, Slic3r, and RepetierHost->curaengine. Printed without support at .2mm layer thickness. --Update 2015-04-25: I increased the size of the front holes to fit M3 nuts. Also, I modeled some supports and moved the hotend cooler 4mm lower. Now it's even easier to print and assemble. --Update 2015-06-20: I changed many diameters and spare places. Now it sits much better and is slightly more easy to assemble. However, I can't upload new files right now; will come later. A preview of the finished thing is in the gallery. --Update 2015-08-08: Just uploaded the finished version. Any tolerances and spaced got tweaked many times. Now it carries a 40mm fan instead of the smaller one, and it works simply great for me! The only update I might do is apply it to the carriage of the Prusa i3 rework parts, but that will be uploaded as a different thing.
