Cobblebot Vanguard Replacement Parts VOS

thingiverse

So started to design replacement parts, and I'm somehow optimistic that more will follow. Update 07.12.2015: Uploaded z-sliders to fix a lot of issues with the original design. Files are zslider_left6.stl and zslider_right6.stl. Both need to be printed with support structures. Recommended settings are 25% infill and 0.2 mm resolution. Update 08.12.2015: Had to update zslider_left6.stl to zslider_left7.stl as there were some issues with the pocket for the x-endstop switch (diameter for screws too small, length too short). Update 14.12.2015: Added xcarrier_main13.stl and xcarrier_helock13.stl. Provides mount for single hotend, fan, and proximity sensor (LJ12A3-4-Z/BY). Update 16.12.2015: Added corner brackets for the bed-frame. The files are bedframe_bracketA.stl and bedframe_bracketB.stl (mirrored). You need two of each. Update 17.12.2015: Added mount for z-axis stepper motor. The file is zstepper_mount.stl. Update 18.12.2015(a): Added a part to mount the bed-frame to the x-axis rails at the bottom in a squared angle. The file is bedframe_crossmount.stl. You need two of them. Update 18.12.2015(b): Added a second version of the right z-slider, because third-party brass-nuts are slightly smaller than the original brass nut that comes from Cobblebot. Please note that you need either the one or the other: zslider_right6.stl (is for the original brass-nut that comes from Cobblebot) and zslider_right_3rdparty.stl (is for slightly smaller ones, purchased from third party). Update 19.12.2015(a): Added a replacement part for mount of y-idler. The file is yidler17.stl. Update 19.12.2015(b): Added a replacement part for joint mounting of the y-stepper motor and the y-endstop. Note: For easier and cleaner wiring, both electronic parts were put together and shall be mounted at the back side of the printer (idler to the front). The file is ymount19.stl. Sidenote: Some of the STLs have a quite challenging geometry that requires support structures. I decided to design them by myself and not use the slicer function as it seems to create far too many unnecessary supports and gives a hard time cleaning them off. Those additional STLs are available but not yet published as it is unclear if there is someone interested in. Please leave a short comment in case that you want to see them also published. Update 20.12.2015: Updated ymount19.stl to ymount20.stl and bedframe_crossmount.stl to bedframe_crossmount20.stl for minor fixes that showed up during installation. For the ymount, the screw-holes were moved by 1mm for easier installation. The bedframe-crossmount has been "slimed down" as the corners collided with Cobblebot's "5 Point Connectors" during installation. Update 21.12.2015: Added a replacement part for spool holder as it turned out that the first version had too much rolling resistance and didn't work well. The new design uses ball bearings for smooth rolling. The spool width can be adjusted as needed. There are four of those ball bearings required, further more you need four M8 x 30 mm screws and four M8 nuts. The files are spoolbb_slide_25.stl and spoolbb_rail_25.stl. Two of each are required. Update 08.01.2016: Changed the design to dual z-motor support to eliminate x-gantry sagging. This requires the 3D printed parts zmount_right30.stl and zmount_left30.stl, and updated versions of the left and right zsliders, zslider_left30.stl and zslider_right30.stl. Of course you need also a second set of lead screw, brass nut, stepper motor, and motor/screw coupler. From the tests I can confirm that this made a huge step forward into print quality and is worth the effort! Update 06.02.2016: Added a housing for controller and LCD display. Filename is controller30.stl. Recommended infill is 10% with support structures enabled.
