Gapless window roller blinds support

Supports for window rollers that leave almost no gap between the window and shades, making for a much darker room.

Compared to most commercially available supports:

• Distance between roller and window frame is minimal
• An additional guide for the shades to keep them close to the window
• Drill-free design with enough surface area for double-sided tape
• Single design allowing placement of beads on either side

First make sure the design is compatible with your rollers. Pretty much all I could find commercially have the same dimensions, they should be pretty common the EU.

There are files for left and right (it's the same part just mirrored). Print both sides and the guide as they are oriented in the files. Then push the guide into the support, there's a small mark to know when it's fully fitted.

In case you broke or lost the plug that goes into the shaft, there's a design from someone else here: https://www.printables.com/model/67566-roller-blinds-plug-for-window-clamp-holder/files
