Camera Slider / Dolly - Coder-Tronics

Description

Introduction This is the first version of an almost fully 3D printed camera slider, using 10mm O/D carbon fibre rods and 4mm O/D PTFE solid rods as inserts for the bearings. I see this more as a proof of concept as my main aim is to make a small motorised version for time lapse photography, to be used with a GoPro primarily but also other small cameras and phones. I wanted something light so it's good for hiking or travelling and this is also a way of testing the prototype bearings out. There is a short video showing a basic assembly, as well as a quick video test and basic strength test. https://youtu.be/EmyTxzf4ODk Printing Everything is designed to be printed without support, you may have to flip/rotate some of the files to get them orientated (I sometimes accidentally use a different plane in Inventor). I printed all of these at 0.2mm resolution with an infil of 30-40 percent. However, I would uses 50-60% for the end plates as the M3 bolts that lock the 10mm carbon fibre tubes, can split the layers if over tightened or if you have weak layer to layer adhesion. Turning the heat up to the upper end of your filaments temperature range can help with this. I have also included .STP files as this might make it easier for anyone who wants to tweak the design. Required Parts Bearings 4mm PTFE rod - each bearing takes 4 x 30mm of rod, so 480mm in total. PTFE tube may well work here, but not tested as the rod was cheap from a UK supplier (far cheaper than Ebay or Aliexpress)…
