Ender 3 Frame plug for Teaching Tech Control Box

thingiverse

Note that this does NOT fit the Ender 3 pro! I've just upgraded to the SKR Mini E3 32-bit control board from BigTreeTech, and installed it into Teaching Tech's well-designed all-in-one universal electronics case (thanks Michael). I was very pleased with the results, but I hated the (now empty) notch in the extrusion frame where the wires to the original front-mounted box used to go. This is my solution to plugging (and camouflaging) the aforementioned notch. It is simply slipped into place and held with a few dabs of cynoacrylate glue. It also provides a cable route for the Z-axis home switch wire (for the savages amongst us who have yet to purchase an ABL system!). As a bonus, I feel that it has reduced the noise of the airflow through TT's case by ensuring the air is now only drawn through the vents on the underside, and not through the dirty great 'ole in the frame! I first designed it as a simple extrusion-shaped shell with no upper face, but I found this was prone to snapping when removing the supports needed for the cable channel. So the current design incorporates a thicker body with curved faces to add strength. Rev1 = I have now squared off the corners (instead of the curves in the pics) to match the true shape of the frame extrusion fitted to the machine. Rev2 = Additional tweaks to more closely match the Ender 3 frame extrusion. Hippy Pranting!
