This Thing will block your windows from closing due to draft. You can put foam on the edge of the window blocker to cushion everything.

• The thread and the bolt is an M10 thread with -0.2mm offset (-0.4mm in total) on upper and lower part of the thread to add more clearance.
• The middle layer of the thread and the bolt have a filet of 0.15mm.

Remember that on most slicer you can cut the height of the block if that to bif for your windows.

IMPORTANT :

You can print this block in different orientation, but try not to add support to the threads, otherwise the bolt may not be able to screw in properly.

I personally use organic support.
