Clips for attaching a spring between 5mm diameter carbon push rods on Kossel printers. These help to take up the play in the rod end bearings, and also make the printer run a lot quieter. These were designed for the Anycubic Kossel Linear, but would suit others with 5mm rods.
If the rods are about 50mm apart, the distance between the holes for the spring would be 35mm. The springs I used were about 25mm length when relaxed, and came from this set: "Rolson 61298 Spring Assortment - 150 Pieces" (https://www.amazon.co.uk/dp/B000QF7JTO/ref=cm_sw_r_cp_ep_dp_UdMIybW8H53H6)
I've also uploaded a "long" version which extends the clip length by 5mm (to suit wider rod spacing).
Update: I've now added an improved version 2 (long_v2) with the clip rotated to have more load bearing surface directly opposite to the spring (therefore less likely to pop off) and with slightly rounded edges for purely cosmetic reasons ;)
