Craftbot Hidden Hinge for a Front Door

thingiverse

When not in use, the hinge is cleverly concealed and requires two pivot points to open it up. This also means you need to push the door to the right before turning it fully open (still brainstorming ways to improve that). The design calls for screwing it into place on the side panel with an existing screw, fitting snugly onto both the right and left sides of the printer. If the hinges are giving you trouble, try reducing your print flow rate to break them free. I've also included the .dxf file for cutting out the acrylic front door. Feel free to modify it if you'd like to add a handle (I seem to have forgotten about that myself). I printed the design with 100% infill to maximize its strength and omit any supports. The holes are designed to accommodate four M4 screws, which I've paired with two strong magnets at opposite corners, secured in place with 2K epoxy to keep it closed. Update: After some consideration, I wasn't entirely convinced that a glued handle would hold up well over time. So, I quickly drew an alternative design that utilizes the existing M4 screws instead. It's a bit unconventional since it mounts on the opposite side of where you'd typically expect, but it works surprisingly well. Update2: I've noticed that some folks have had issues with the tight tolerances (particularly when printing with ABS), which led to fused parts and unusable results. To address this, I added an updated version with slightly enlarged tolerances (+0.5mm for hole diameters and +0.5mm between top/bottom and middle parts).
