MPCNC Bosch Quick Release & Vacuum Mount

thingiverse

9/2/2018 Update Someone asked about the C-525 version again, and I'm finally upgrading myself to this version, so I added BoschMount_X_C-525_Rev37.stl & BoschMount_Y_C-525_Rev37.stl files to make it easier to sort out. Print one of those depending on which orientation you want the vac connection on. All other parts should be the same. 5/22/2017 I fixed my problem with the vac connection and made it part of the quick disconnect. I'm pretty happy with it now. I ran a 1.5 hour cutting job with no problems. I also got rid of the slanted cut for the top of the router mount as it did not seem necessary, and also allows you to rotate the router the way you want it. 3/18/2017 Looks like I need to shorten the height of the bottom vac attachment. Don't know how I missed this, but the bottom of the vac piece is too low unless you have a long router bit. I will revisit this design next week to see if I can shorten it the correct amount. Meanwhile, I have deleted the bottom vac attachment from this design. I started updating my vacuum connection recently for the MPCNC that I have after finding this interesting idea for a dust shoe. http://www.thingiverse.com/thing:200583 After remixing it, I realized I could make this in 1 part instead of 2 & print it without supports. About the time I finished doing this, I came across a quick release mount for the Bosch, http://www.thingiverse.com/thing:648883 I initially did not see that someone else had remixed this to work on a MPCNC. The original design worked pretty good without any alterations. The major changes I made to the quick release design were to make the 2 cams only 1 part and made the cam about 1mm longer with a flat part of cam to hit the arm which held it in place better for me. That wider flat part where it hits the arm made a big difference in having a snap fit. You can hear this snap in the video I uploaded. Using a wider cam instead of the 2 smaller cams also made this connection more solid. For the 2 part mount, I added the 10 degree slant cut to fit the Bosch rather than having it even at the top. If you do not want that, you can comment it out in the openscad file. I printed most of the parts in eSun PETG, but did print the bottom vacuum connection & adapter in PLA. In addition to the Vac_Adapter_32_8Ang_Rev20.stl that puts the vacuum hose vertical, I added a 30, 45 & 57.3 Angle adapter to use at different angles. I included the openscad source files along with the STL files. The profiles for the vertical 3/4" EMT connections are in a DXF file which should make it easier to adjust for another EMT size. STL files to print: BoschMount_X-Axis_Rev36.stl (50% to 60% infill) armWithVac_X-Axis_rev36.stl (50% to 60% infill) or BoschMount_Y-Axis_Rev36.stl (50% to 60% infill) armWithVac_Y-Axis_rev36.stl (50% to 60% infill) or for C-525 version along X-axis BoschMount_X_C-525_Rev37.stl armWithVac_X-Axis_rev36.stl or for C-525 version along Y-axis BoschMount_Y_C-525_Rev37.stl armWithVac_Y-Axis_rev36.stl Optional parts to print: If you need the tool holder nut & drilling guide for this configuration, I included the STL files: Tool_Holder_Nut_Trap_x2_76_2mm_28mm_rev1.stl Zpipe_DrillGuide_rev5_x2_76_2mm_28mm.stl There is also an image showing the nut trap spacing for further clarification.
