DIY Dremel CNC #1 - My Mod Collection (Dremel 4000 mount, New Z-axis, End Stops/Drag chain mounts and more)

thingiverse

This is my collection of modifications for the DIY Dremel CNC #1 from Nikodem Bartnik. You can find the assembled machine that uses these parts on Thingiverse: (https://www.thingiverse.com/make:641672) Overview on the parts --------------------- * Dremel-4000-Spindle-Holder_v12 This modified version of the original Dremel makes it easier to use the power switch and eliminates collision with the Z-Axis holder when in the upper position. The center hole for the Dremel has been reduced slightly for a tighter fit. * Z-Axis_v6 This modified Z-Axis simplifies installation of the end-stop for the Z- and X-axis, as well as the mount for the drag chain on the X-Axis. An additional hole is provided for the lead screw nut to prevent it from sticking out on the x-axis. * Mount-Drag-Chain-X-Axis-Long_v2 A mount for a drag chain on the X-axis with outer dimensions of 10x20mm. Attach this part to the upper portion of the backside of the Z-axis (screenshots show pre-drilled holes if using my modified Z-axis). * Mount-Drag-Chain-X-Axis-Short_v6 A mount for a drag chain on the X-axis with outer dimensions of 10x20mm. Attach this part to the X-axis carriage on the right side, using a small drill and M3 screws. * Mount-Drag-Chain-Y-Axis_v5 A mount for a drag chain on the Y-axis with outer dimensions of 10x20mm. Attach this part to the "outer" side of the X-axis carriage with three screws (use a drill and M3 screws). * Mount-End-Stop-X-Axis_v2 A small mounting bracket for an end-stop, measuring 19.8x10.2x6.4mm. Use M2.5 screws to attach it directly to the bracket. * Mount-End-Stop-Y-Axis_v4 A mounting bracket for an end-stop, measuring 19.8x10.2x6.4mm. Attach this part directly on top of one of the rods for the y-axis and secure with M3 screws and nuts on the rod. Use M2.5 screws and nuts to secure the end-stop. * Pad-for-End-Stop_v1 A tiny part that can be pushed onto the end of the lever for the end-stop. While not essential, these pads ensure good contact between the lever and parts (especially on the Z-Axis). Note that this part will only fit if your lever has a small bend at the end (radius 3mm). * Remarks All mounts for the drag chains have holes where you can insert M3 nuts to make it easier to attach the chains. The drag chains visible in the pictures measure: Outer: 10x20mm Inner: 7x15mm R28 All parts are available in STL and STEP formats.
