Parametric Parts for CNC Router and 80/20 Extrusions

thingiverse

I've got a lot of miscellaneous parts I designed for my CNC router build (https://openbuilds.com/builds/fixed-gantry-cnc-router-with-old-industrial-supplies.6742/). I used 8mm leadscrews, 16mm linear rails, a 16mm ballscrew, 80/20 series 1530 (1.5" x 3") extrusion, etc but all the files are parametric so they should be easily adaptable to other sizes. I've included here: router_mount.stl A mount for holding a 64mm diameter cylindrical object (such as a Harbor Freight trim router) and mounting it to something with 4 SAE #10 1.5" machine screws (such as the z_mounting_plate below). x_nut_connector_v3.stl Used with 2 SAE #10 machine screws and t-nuts to attach aluminum extrusion to a standard 8mm leadscrew nut. x_pillow_block_spacer_v4.stl A small spacer for something with 42mm mounting holes (such as an 8mm pillowblock). y_guide_drill_template.stl y_guide_drill_template_half.stl y_guide_drill_template_half_trimmed.stl A drilling template for use with 4 linear rail guides with 4 mounting holes each. It was too large for my print bed so I trimmed it and cut it in half. And then I changed the layout slightly and decided to just 2d print the new version on paper. y_nut_mount.stl A mount for a 16mm ballnut (1605). z_mounting_plate_2_guides_v2.stl z_mounting_plate_v4.stl Mounting plate for connecting a router mount (such as found above) to either 1 guide per side or 2 guides per side when the guides are sitting on linear rails mounted to the outside of 80/20 series 1530 aluminum extrusion (see pictures). This might work in some situations but I found there to be too much side-to-side play so I used a different z mounting plate after moving the rails from the side to the front of the aluminum extrusion. z_nut_mount_v2.stl Used with 2 SAE #10 machine screws to attach a standard 8mm leadscrew nut to the z_mounting_plate above. Should be a drop in part for the OpenBuild anti-backlash nut for 8mm leadscrews (http://openbuildspartstore.com/anti-backlash-nut-block-for-8mm-metric-acme-lead-screw/). The anti-backlash nut didn't initially seem to fit my 8mm leadscrew purchased elsewhere but after a few dozen insertions/removals, the leadscrew reamed out enough plastic to work. z_stepper_motor_mount_revised.stl Adapter to mount a NEMA 23 stepper to the end of an 80/20 series 1530 aluminum extrusion. The adapter is secured to the end of the extrusion after tapping the holes and the stepper is secured to the adapter. See photo.
