Draft Dodger Extension Tube

This is an extension tube for the Draft Dodger 12" mail-slot.  I believe it was originally designed for a door, but mine was mounted in a mud-room wall and I needed an extension tube to prevent mail from getting stuck in the wall!

The print ended up detaching from the bed and the walls split in the middle.  However, I didn't want to re-print so I used box-tape to ensure it stayed attached to one side.  Sorry about the pics - I should have taken some before I put the tape on!

I also used a ABS which may have contributed to print issues.

Next time, I would use more glue on the bed, enable raft and possibly increase the wall thickness.
