A modular wall-mounted cat tunnel.

UPDATE:

NEW MAIN TUBE: I have added a new main body section incorporating the mounting holes for better stability. You can choose to print the original main body with the separate mounting bracket or the new main body with mounting holes incorporated. All pieces remain compatible. 

NEW CORNER SECTION: I have added an inner wall corner section that works for both left and right inner wall corners. You must print the the new coupling in order to connect the corner section to any main section.

NEW END SECTIONS: one flat and one rounded end section. I will be adding new end section for a larger dome piece.

Instructions:

note: I'm aware the flat disk windows that I have referenced in the description have a loose fit. If there is enough interest or requestes i'll release a fitting to make them fit better but I've noticed my cats like to poke their heads out of the openings so have decided to forgo using them. 

The material used in  my photos/examples is YOUSU Dual Color Wood PLA Filament sourced from Amazon.com. Its much softer then regular pla (which is more comfortable for your kitties)  and supports come off much easier. I recommend using 3 outer wall layers for wood pla but 2 walls or the standard pla setting by Bambu Labs slicers are still sufficient. The more units you use the stronger the system gets. 

After printing is complete please use pliers to remove supports. I recommend hitting each large support first with a blunt object off then inserting pliers at the end of each large support to pry it off. Most supports will come off clean but for any difficult support (specifically the large vents in the front) I recommend using a utility knife. Wedge the utility knife in between the main body and the support. Do not score the knife. Then proceed to use pliers to remove the excess support material.

1. Print the largest object (the main body). Then proceed to print additional bodies as needed.
2. Mount each body with the small rectangular mount with 6 holes. You do not need to use all 6 holes to mount. I recommend using only to hole vertically. If you're mounting multiple units I recommend just securing every other unit. Make sure to use anchors if not mounting on wood studs. Screw holes are designed for 3" x #10 screws.
3. I recommend printing and installing at least 2 or 3 modular units if installed independently from any other cat wall furniture.
4. Please, print the accessory end units, for the start and end of the overall tunnel even if its only one, two, three, or how many bodies you decide to print, to reduce the risk of injury for your kitty due to the sharp edges.
5. I supplied links to the dome which can be installed in the front of the main body and the disk which can be installed at the bottom floor of the main body. You can install any 5" diameter circle or dome in the front up to 1/8" thickness. You can install any 4" diameter circular disk up to 1/4" for the bottom hole insert but to achieve a flush finish with the bottom hole and body the disk must be ¼" in thickness.

6. You can assemble as many units as you please to achieve your desired length. Make sure to use install end units at the beginning and end of the entire tunnel (not per each body).
