M5 Bontrager/Trek thumb screw
prusaprinters
Simple alternative for the extremely expensive (and imho bad) frame screws from Bontrager to attach frame bags to the bikes (e.g. Trek Checkpoint) → https://www.trekbikes.com/gb/en_GB/equipment/bike-accessories/bike-bags-panniers/bontrager-thumb-screw/p/37387/The original ones are made of steel, which in combination with the aluminum threads of the frame in the ALR or SL version is an incredibly bad idea. Aluminum or plastics would be the better choice. So here it is at an price tag of about 1% of the original price. Even tough I printed them with PLA and they still go, I suggest to use ABS for longer durability.
