CTC Bizer Dual (and others) doors and lid

thingiverse

This project started with the hinges I found on this platform. From there, it progressed into completely closing my CTC with doors and a lid/top-cover. I had planned on adding hinges to the lid as well but decided to keep it separate from the printer so I wouldn't have to drill more holes close to the y-axis rod. The lid, when opened, would need to go further back than the position of my printer allows, so now I just take it off and put it aside when necessary. I didn't change the hinges but did redraw them in Freecad. New stl files are attached. The DXF files are the cutting templates for the doors and top-cover plates. The front doors are a bit larger than the front opening, while the side doors fit into the side openings. I used 3 mm acrylic that I cut by hand using a special knife. Laser cutting is preferred. Because of the thickness of the acrylic, I added spacers between the hinges and the doors. Six millimeters for the side doors and three millimeters for the front doors initially. I later changed them to two millimeter spacers for a less tight fit. I made drill templates for the printer case and for the doors. They can be mirrored by physically turning them around, so you need just one for each door/side. On the top-cover, I used the corner parts as a drill template. You'll need to tape it together first to ensure all plates are positioned right. I screwed everything together using M3 nuts and M3 allen bolts (M3x8, M3x10, M3x12 & M3x16). The knobs allow use of round magnets (12 x 2 mm). You can then put some flat iron screws in the case that will allow the magnets to snap into place. For the top-cover/lid, I used brushes from the local hardware store. These brushes are used in Deltafix mailbox weather strips and are easily cut to size. They slide in the brackets perfectly. This design is a result of the filament holders I decided to use. It allows the filament and extruder cables to go through while keeping the entire setup closed.
