After searching several solutions for a CC1 Top-Cover for my new Canvas, I found the one from M.E Wolters, which I liked most. https://www.nexprint.com/en/models/G6224565 (used the Version 2026-05-03)

It came out great, but as it didn't fit perfectly, I designed/remixed some additional “helpers” to fit my needs.

Glass/vents/ventcover:

I wanted to have vents for a better cooling when printing PETG or PLA, so I took the measurements from M.E.Wolters and tried to design a printable glass-inlay. The idea for the vents came from here which I remixed into my design:

https://cults3d.com/en/3d-model/tool/centauri-carbon-1-riser-testing-for-canvas . If you want to print the vent covers, you can take them from the original model on cults3d and mount them with magnets. 

Ground-plate:

The printed parts didn't fit very good to the original ground plate, so I took parts of my old printed “low riser” and modified the front, left and right side to fit the canvas and to avoid bumping the printhead into the old riser. (original model here: https://makerworld.com/en/models/1626882-centauri-carbon-low-riser-with-slideable-lid )

Canvas mounting plate:

As the Canvas-cover was a little too big (I didn't measure before printing in advance) I needed to tinker a ground plate for mounting on the canvas itself. (see separate canvas_deckel_unten.3mf )

Filaments: Jayo Petg Matte Skyblue and White for the hat, Grey for the Canvas-plate, and Bambu Petg Translucent for the glass and the canvas-hat
