This file creates two types of hinge to replace the original poor quality Catalac (Catamaran) hinges on the lockers that were made with thin ABS. One was a typical triangular hinge made for economy by using the same part twice but this left the hinge weak. The other style was the T style hinge which was a cleaner design but still poor strength and way too thin.
This is a very custom-izable generic hinge generator that also allows changes to the hinge elements by specifying the number of slots on the larger hinge (the one with a cylinder and pin hole on both ends). Clearances can also be set for both the radial and axial directions and the hinge body can be offset from the cylinder while retaining the original hole positions.
All the hole positions are calculated and verified.
My recommendation is to make the part stronger than the original by making it thicker. The webbing on this design is already stronger than the original but if you're going to make new hinges, why not make them last. I've left the original dimensions in the comments section.
The program places the hinge pair with a small clearance between them but it can be modified to print one section at a time to make better use of placement on the printer bed.
This is not an all purpose hinge but can be adapted to one by reducing the webbing height. As it is now, the webbing restricts the angle of movement, trading freedom of movement for added strength. In this application, the lockers open up just over 90 Degrees, it works without restriction.
Use UV rated filament as it's meant for outdoor use.
ABS is not suitable, nor is PLA, PETG is probably the better choice.
The original hinges were removed and measured with digital calipers.
The hardest part in the programming was the slots and lands on the hinge cylinder.
The complications there are subtle, there are the axial and radial clearances to consider and the part needs webbing to reinforce the hinge to the cylinder.
I went through two different revisions before settling on this design as it gave the best model with the fewest artifacts and the most versatility.
