Nodal Ninja 3 kit to provide 6 degree detent

thingiverse

A friend in the US asked for a high res image of Sydney Harbour Bridge and Opera House for blowing up to about 4ft x 8ft. The minimum angle available on the standard Nodal Ninja 3 detents is 15 degrees which was not fine enough for my needs. Hence this design which provides a 6 degree detent. And here is the result: https://flic.kr/p/WYwKkf Designed in Moment of Inspiration (Moi3D) and printed in PETG on a Prusa Original i3 Mk2 and on a Kodama Trinus. Simplify3D slicer used for the Trinus and Prusa Slic3r used for the Prusa Original i3 MK2 4 colour. The detent plate and the pin need to be made from a 'hard' material. I think that PLA would be OK but I doubt that parts made from ABS would last very long. The design needs hardware. I used: 7-off 3MM x 10mm long button head cap screws 1-off 6MM x 35mm (under the head) socket head cap screw 1-off compression spring. 7mm diameter, free length 20mm, solid height 5mm. 6 full turns. Wire diameter 0.5mm. A brief video is here: https://youtu.be/JPQH2QBTUew
