Discvice (frisbee clip)

Motivation:

In the past I have used those frisbee clips that are a solid one piece and sort of slip around the frisbee. I find those difficult to put on the disc and very prone to slipping off while walking around.
I also hate when the disc swings while walking so I would use multiple of them to stabilize the disc on my bag, but since the one piece clips allow the disc to slide, they all end up on the top of the disc and the swinging returns.
So I designed this model that is based on a vice grip (locking pliers). This model is in my opinion easier to put on and take off and will hold the disc more firmly.

demo:

Here I only have provided the stls for the individual pieces and the assembly. I created this using openscad so it is parametric and can be customized using openscad's customizer.

I could not include the openscad file here because it depends on some libraries so instead I can provide the repo where I have the code.

NOTE:

this only works with Discraft Ultrastar discs (or other discs with the same lip shape)

Assembly:

hardware required:

M3x0.5 8mm flat head screws are required for the stls that I have provided here. If you are familiar with openscad you can try tweaking that along with other things if you go to the repo.

Printing:

You can print the individual pieces (with supports) and put everything together afterwards. But I hate post processing and it takes longer so instead I like to print the assembled model with 0.2 mm layers**. and if your print settings are good the individual parts should crack free after working them a bit. Usually I insert the screws first then wiggle until it cracks free.

** Printing in place works better with 0.2mm layer height through the gaps between the different pieces in the assembly. To make the print faster I set the layer height to 0.3mm everywhere else though.

I have been using PETG with 40% infill and have had pretty good results in terms of durability. I have these on my bag all the time in the elements during ultimate tournaments, but I expect they will break eventually. I don't recommend PLA as it will deform in the sun which is where my clips are a good chunk of the time.

summary of recommended print settings:

• print assembled version (support on build plate only. mainly for the linkage arm). if printing un-assembled version there will need to be supports
• 0.2 mm layer height
• PETG
• 40% infill (less will work but the vice will probably break sooner)
