Downhill mountain bike-Dual suspension
This is a miniature model of a downhill mountain bike, it is an updated design following our widely successful first downhill mountain bike model.
It has working front and rear suspension as well as rotating wheels and rotating cranks and pedals. This model has been designed from scratch with optimal 3D printing in mind.
Print level: Expert
Infill Level: %
Model originally printed on: Makerbot Replicator 2X
Recommended print settings:
The frame (including the bottom bracket) prints all in one, then simply remove the support and put a small amount of pressure on the linkages and you will hear a 'cracking' sound indicating the the linkage is now free of supports and should easily pivot. See the photos for where it is recommended to put the support structure to get a nice successful print. The front forks require some assembly, print out the separate parts, slide the springs over the 'Front forks lower' and then place the 'Front forks lower' into the slots in 'Front forks top_back' then clip the 'Front forks top_front' into the 'Front forks top_back', they are a press fit and can be secured with a bit of glue if you never want to take it apart (maker sure the sliding mechanism doesn't get any glue on it). See pictures for a visual guide on how to assemble the front forks. The rest of the parts should all slide on, the pins through the wheels can be glued if you want a super solid bike.
Since this model is stressed when you use the suspension it is recommended to use 3 layers with a strong infill pattern of between 20-30% infill. This is especially important for the springs which take a lot of stress.
