Centauri Carbon CC1 canvas lid made from a plastic box

The original design lacks information on the construction process. I'm therefore adding some information here.

The square box is from Action : https://www.action.com/fr-fr/p/2533849/boite-de-rangement-avec-couvercle-clipse/

The box can be cut using scissors or a utility knife. You can also heat the utility knife blade with a torch.

Step 0 : Print the riser, assemble it and put it on the printer. Print the two parts to be attached to the box.

Step 1 : Remove box cover and black closing flap.

Step 2 : Cut 17cm in the center of the border. This allows the box to be positioned correctly in order to accurately mark out the area to be cut.

Step 3: Mark the outline with a pencil. Then, subtract 1 cm for the attachment area. Hatch the area to be removed.  

Step 4: Cut the area to be removed. Adjust the box on the printer and drill the holes on the printer with everything adjusted.

Step 5: I used M2x8 and M2x12 screws to secure the inner and outer parts. Once satisfied with the attachment, trim off the excess on the inside.

Step 6 : Add the two part to close the remaining hole on each side of the canvas. I use two M2x8 screws to fasten them.

Note : Contrary to original design, I haven't attached the box to the riser, and I'm not using the U-bracket, yet everything is working fine. 

Note, another option is VESSLA IKEA square box : https://www.ikea.com/fr/fr/p/vessla-bac-de-rangement-avec-roulettes-blanc-30064849/
Similar, but slightly larger in size. So things need to be adjusted.
