the end result is great! a little holder I can attach to the bars or frame as a third hand. TPU means no risk of scratches etc. I’ll be printing another to hold the syringe at the bottom. I did have issues printing the pins in PETG. I had to enable a brim and revert to default support settings to allow the ‘ball’ to grip the bed and stop sliding around, which was a tiny bit of sanding. but otherwise a good result
