Holders for hydraulic bicycle brake bleed syringes. Print in TPU. Pin should be printed in a strong material, I used PC but PETG should also work. PLA twists too easily. I recommend printing by object instead of by layer.
Update 10/02/2025: The “generic” 3MF files were exported from Bambu Studio, please keep that in mind if using another slicer. I also updated the design with a split version of the pin for easier printing (glue them together afterwards) and added STLs of all the parts in case you'd like to slice them yourself.
