Description
This project started with the hinges I found on this platform. From there it progressed in completely closing my CTC with doors and a lid/top-cover. I planned on adding hinges to the lid as well, but decided to keep it separated from the printer so I didn't need to drill more holes close to the y-axis rod and because the lid, when opened, would need to go further to the back than the position of my printer allows. 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 template for the doors and top-cover plates. The front doors are a bit larger than the front opening, the side doors fit into the side openings. I used 3 mm acrylic which 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. 6 mm for the side doors and, in the beginning, 3 mm for the front doors. I later changed them for 2mm 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 (Tape it together first to be sure 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) screw is the case that allow the magnets to snap to the case.
For the top-cover/lid I used brushes from the local hardware store. These brushes are used in (Deltafix) mailbox weather strips. They're easily cut to size and slide in the brackets. This design is a result of the filament holders I decided to use. It allows the filament, and the extruder cables, to go through and still keep the entire setup closed.
All the parts:
Doors:
8x Hinge, Hingebracket & Pin; 2 for each door
4x 2mm spacers; 2 for each front door (3mm spacer for tight fit)
4x 6mm spacers; 2 for each side door
12x M3x12; Front door hinge
12x M3x16; Side door hinge
2x Front door knob
4x M3x8
2x Side door knob
4x M3x10
32x M3 nut
Top-cover/lid:
Acrylic plates:
Top plate 400 x 270 x 3 mm
Front plate 400 x 150 x 3 mm
(2) Side plates 264 x 150 x 3 mm
(2) Back plates 170 x 150 x 3 mm
4x Corner inside & Corner outside; for all 4 top corners
1x Rear bridge inside & outside; joins 2 rear acrylic plates
2x LF (Left Front) + RR (Right Rear) inside & outside corners; bottom corners
2x LR (Left Rear) + RF (Right Front) inside & outside corners; bottom corners
70x M3x12
70x M3 nut
Optional:
2x L+R Brush holders; Left & Right brush holder
1x Rear brush holder: <--
Printer:
CTC Bizer Dual
Rafts:
No
Supports:
No
Resolution:
.2 mm
Infill:
100%
Notes:
I used 100% infill, but this might be overkill.
I only used supports on the front door knob because the magnets hang over the 3mm acrylic doors.
Some of the hinges and hingebrackets needed some work to make them fit smoothly.
