Lego Duplo to Hot Wheels Hinge Adapter

(Debuted at #mrrf2018)

This will adapt hot wheels track to duplo lego with a +/- 45 degree pivot angle. When this is printed it does take some force to break the hinge loose. This was designed to be able to relatively hold the angle it is set, hence why it takes some force to break the hinge loose. The base is designed to have an optional M5 x 6.7mm McMaster Heat set brass insert if you would like to mount this to anything.

Step file is included if you want to modify the design. Best p
