I haven't seen Kevin (Mindtrik) around here on the forum much this year. You might try PMing him. I used these last year and they are great.

If you can't get in touch with him, 3 of his 4 designs are available on Thingverse. Maybe somebody here from the forum with a 3D printer could print some for you. Or maybe you could have them printed locally.

I will try and contact him by email. My clips were a custom design that he only made once for me and I need a bunch more.
