Description

I needed a lamp mount for my bike. This is what I came up with.

See the video of the creation here:

Designed in catia: 45min
Print time: 80min

Thank you very much! That looks fantastic!

Volume is reduced from 20 cubic centimeter to 11

Sorry I made a silly mistake! I was removing material from inside so it wouldnt clamp! :) I modified the parts so now should be OK (30mm internal diameter). I have replaced the models in the link

Just for practising I have created a Finite Element Model based on yours. I have applied a 0.5 Kg Vertical force on each Fixing Hole (total 1kg) which is way too much above the light weight, but can be considered as an "accidental" load while handling the bike. For Fused Deposition Modeling ABS Plastic I have used the average tensile strength of 18 MPa (as extracted from this nice article: http://ode11.com/publications/...

Results are here: https://plus.google.com/photos...

Maximum Displacement is 6.4 mm on the extremes

Maximum Von Misses Stress 1.39 Mpa, thus not permanent deformation (18MPa) is achieved. Maximum Displacement is 6.41 mm on the extremes.

If adding a 1.5 mm radious as shown in the images the Von Misses Stresses and displacements are slighly reduced, The Images have an scaled factors to exagerate the distortions

This is not of course accurate (the full set of analysis) since Im a beginner on this subject

WOW! That is incredible! Thank you very much. I think now we can say that the bikelamp won't fail. Since my design is waaay over designed, it would be interesting to see how far I could reduce thickness before plastic deformation occurs. What program did you use to simulate the stresses?
