PinClaw Rubber buffer
This is an easy spare part for the PinClaw by Vertitruss.
The tool itself is great, but it does come with quit bad rubber buffers for not scratching the metal framing.
I recommend printing it in TPU with low speed in 100% infill to get the best results and strongest material. Therefore, I recommend not setting the infill to 100% but increase the number of walls to have an even print.
