V-Slot Covers now flush with extrusion (optional) - fully customizable

thingiverse

After receiving several questions on how to make the customizable v-slot covers of Kerb Orbiter flush with the extrusion (had left a comment there), I decided to upload my modifications as a remix. (Many thanks to [Crabiter](https://www.thingiverse.com/Crabiter) for sharing the .SCAD file I could start with (and sorry for using your ring picture, I had my covers already replaced by flush versions without taking a photo before)) I preferred to have the cover flush with the frame instead of letting it stick out, i.e. lie on top of the extrusion. Especially at the x- and y- belt axes this is beneficial to avoid any problems with the moving carriage. Therefore I split the `cover_thickness` into `outer_thickness` (on top of extrusion) and `inner_thickness` (inside the slot). `outer_thickness=0` will make them flush with the extrusion. Now you have 3 main options for covers and screws: 1. Rings around the screws (requires `outer_thickness` > 0, two layers recommended) 2. Flush with the extrusion (`outer_thickness=0`) 3. Complete coverage of the screws, only cutouts below (requires `outer_thickness` > 0 again) Only downside of the flush version is, that rings are not really possible and covers will fall into pieces, but the covers work still fine Besides the option to make the covers flush with the frame, I also decided to simplify the .SCAD file without the need to consistently maintain several arrays for holes, rings and cutouts. Now it is sufficient to define hole and ring size once and use only one array with the screw locations. Holes, rings and cut-outs for the screws will automatically be created. Additionally extra cutouts can be defined, e.g. to leave space for the end cap plug, which partially blocks the slot for some models (e.g. the CR10V2). These can also be defined in a single array with from/to pairs: `[ [from, to], [from, to], ...]` For those who do not want to use OpenSCAD to create .STL files for their printer, I uploaded some samples for screw holes (single or double screw) and a generic 10cm piece, which can be scaled according to the size of the printer. All these models are optimized for standard 0.2mm layers and 0.4mm nozzle, with 0.8mm walls and 0.6mm cover thickness. Models named '..-ring-..' or '..-cover-..' sick out 0.4mm (`outer_thickness=0.4; inner_thickness=0.2;`). the models name '...flush...' are (guess what) - flush with the extrusion, i.e. `outerthickness=0; inner_thickness=0.6;`. I will also continue to upload models for Creality CR-10(S) and CR10-V2 printers (unfortunately they do not have the same size everywhere). And if somebody provides exact dimensions for Ender 3, I will be happy to upload those as well - I don't have an Ender 3 myself. Update 2022-01-17: I've started adding .stl files for Ender 3 based on measurements provided by [Nolemgib](https://www.thingiverse.com/nolemgib) (top: 25cm with screw holes, bottom 13cm with cutout at one end, vertical half 20cm (40cm can not be printed), but I don't know the positions for the screws holding the power unit, i.e. I can not provide cutout for these)
