This part allows you to hang and remove fabric for use as a shade covering, a wall hanging or around an object. It is meant for semi-permanent use.
Snap fasteners are commonly used to mount canvas, sunbrella, coolaroo or other fabrics to fixed surfaces.
Snap fasteners are fairly expensive. Some commercial fasteners we have been using to hold up shade cloth have failed and need to be replaced. The shade cloth fabric is approximately 0.6mm thick. This design should work for anything that size or thinner.
Since we have a 3D printer, Fusion 360 and helper cats this seemed like an ideal project. The only downside was not having certified UV resistant filament. In this case black PETG was used. Lexan or Nylon should be a better material.
ColorFabb Black PETG was the best material I have available as it is theoretically the most UV resistant of what I have.
I used a standard Prusa I3 in a lack enclosure.
The fitment between the parts came out “most excellent” and the parts match the Fusion model.
How it works
The base is attached to a “permanent” structure (example: a wall), the snap is attached to the base, the fabric is pushed on the needle of the snap, the "fabric lock" presses over the needle and locks the fabric in place.
Use a small screwdriver to remove the snaps from the base.
The PET-G can be painted with a UV resistant paint.

Design and Parts
There are three parts to that work together.
Base – This is the “permanent” part. It is modeled after a standard marine fastener with a wider base in case you want to use adhesive (example: 3M VHB Tape adhesive) for mounting instead of the screw hole. If using a screw please drill the screw hole out to the proper size.
Snap – The snap has two functions
a. It snaps on to the base. There is a gap between the base and the snap to allow the insertion of a screwdriver or some other tool to provide a means to separate the snap from the base.
b. It has an embedded “needle” that is used to provide a guide to where the hole in the fabric will go, or depending on the fabric can punch the hole. This is a small hole. Note: You are solely responsible if you cut yourself.
Note: The snap should be able to attach to commercial fasteners.
- Fabric Lock – This secures the fabric and is pressed over the needle. This is a tight fit and the needle will most likely break in any attempt to pry the two apart.
