Protective/supporting caps for creating triangle-based structures using our LED bars and rope.
For camp 2023 we wanted to build a structure using LED bars based on pipes we already have and rope running on the inside of the pipes. 3 pipes will be assembled to form triangle and the triangles will be assembled to create shapes. For this, the ends of the pipes need a proper load bearing area and also some protection for the cables running on the outside. This repo contains 3D printable end caps which will hopefully do that job.
- WIP, the version we are currently testing/improving
- the version we used for CCCamp in the end
- changed top side from round to 30° edge as else the rope and the round cap create a turning moment that pulls out the caps
- this fixes that round cap makes rope too far off pivot point, so cap wants to twist out of pipe
- also makes everything a bit more stable (line load vs. point load)
- threading rope works OK, a bit fiddly for multi-rope pipes
- still kind of fiddly to set up with all the rope threading, but worked OK
- still very sturdy with 60% infill
- prints completely without supports
- chamfers make cap nicer and more cable friendly
- round cap makes rope too far off pivot point, so cap wants to twist out of pipe
- 'cap' design would probably also have this problem when tested with rope
- inner diameter looks good
- chamfer on inner hole makes first layer hard to print and stick for middle portion (single line circle)
- threading rope seems to work nicely
- still sturdy middle portion (100% infill)
- sits well on pipe
- cable protection ok but, sharp edges should be chamfered
- needs support, but we might be able to drop this
- hole in middle needs to be bigger
- threading rope might be difficult because of edge, might need chamfer on the inside
- currently too small inside plug (radius/diameter mixup by accident)
- does not really protect cables, needs to be longer
- prints faster
- needs support
- hole in middle needs to be bigger
- threading rope might be difficult because of edge, might need chamfer on the inside
