Vertical paint rack for flat surfaces

A paint rack that can be put on flat surfaces.

This design was originally intended for 0.8mm nozzles, but I've included also the models for 0.4mm nozzles.

Generating your own paint rack

If you want to generate your own paint rack, you need OpenSCAD.

The scad contains the following adjustable variables:

// Possible values: 
//  - SLOT_0_4_STL
//  - SLOT_0_8_STL
//
SLOT_STL=SLOT_0_8_STL;

// Specifies the size of the paint rack
RACK_SIZE_X=5; // Columns
RACK_SIZE_Z=4; // Rows

// Adjust the base size where the rack "sticks" on
FLOOR_SIZE=1.2;

// The size of the additional padding applied to the base.

// It's coloured for debugging purposes.
PADDING_FLOOR_TOP=15; // red
PADDING_FLOOR_LEFT=3; // green
PADDING_FLOOR_RIGHT=3; // blue
PADDING_FLOOR_BOTTOM=5; // pink

Disclaimer

The print does not come clean enough, even for 0.8mm, and some overhangings do appear, eventhough PrusaSlicer doesn't indicate so.

The 0.4mm has more over-hangings than 0.8mm with layer sizes below 0.15mm, but I don't think nobody wants to spend more than 17 hours…

Also, the FreeCAD files are still somewhat messy, but less messy than previous iteration.
