3018 CNC Engraving / Milling Machine Accessory Set

I recently acquired a compact CNC Engraving Machine, which they call a "Wood Carving Milling Engraving Machine," but I suspect it won't be doing any heavy milling. That's perfectly fine with me since I already have a couple of 3D printers and a laser engraver/cutter. This is the model I picked up: https://www.amazon.com/gp/product/B074PS7ZP6/ref=ox_sc_act_title_1?smid=A16P4TUM521SQ8&psc=1 Before getting too far, let me give credit to CaptainObvious. I did a partial remix of his "Clamp set for 4030 CNC Router" thing on Thingiverse: https://www.thingiverse.com/thing:901649. I used the design as a starting point and modified it to work with 3mm hardware. The X endstop mount attaches to the top extrusion on the frame, and the switch is activated when the side of the X carriage hits it. The version I uploaded includes a small channel for wire routing. I replaced two of the spacers under the Z stepper motor with the Z endstop mount. The Z endstop switch is triggered by the Z carriage, which works well despite being tight. To manage cables, I used some split loom to keep the wiring going to the carriage tidy. The split loom clips into the spacers, and I tried to keep the spindle motor power lines away from the stepper lines. You can use X_Nema_Cable_Mnt to replace two of the Z stepper motor spacers, keeping things separate using Cable_Spacer and securing the board ends of the wiring to the frame with Cable_Spacer_Frame_Mount. I remixed CaptainObvious's design again to create better workpiece clamps. They're much more reliable than the ones supplied with the machine.
