3D Print Timelapse Video

Few days ago I've decided to do something new: timelapse video of a 3D print. It's kind of fascinating to watch extruder places layer after layer of molten PLA… too bad it's taking so long to print something bigger…

  • Thing: 35 deg RunCam HD / Mobius stand for mini-quads
  • Filament: PLA

3D Printing: rubber launched glider

3D Printers give almost endless possibilities and 3D printed gliders can be a great weekend project. Last week I’ve printed a small fleet of Monarch XL gliders from Thingieverse. Single glider takes around 45 minutes to print at 50mm/s and few additional minutes to glue all the parts together. Add an hour for a rubber launcher and done. Great fun for a small price. It flies surprisingly well and my daughters loves them.

Flight characteristics improves when dihedral is added. Also elevator can be adjusted, so glider can do loops! Great fun for a very low price!

3D Printed RunCam HD / Mobius camera mount for Reptile X4R 220

After I finished my new Reptile X4R 220 racing mini-quad, I've realized, that there is no way I will be able to mount my RunCam HD on it. Comparing to ZMR250, 220 frame is just small. On a top plate there is enough room to fit battery, RC and FPV antennas and all what is left is around 35mm in the front. Plus, with angled FPV camera, there just no place for RunCam HD/Mobius form factor cameras. So, some time with 123D Design and few hours of printing, and here we are: 25 degrees mount for RunCam HD and Mobius camera specially designed for Reptile X4R 220 frame

This mount has 25 degrees inclination, will fit both RunCam HD and Mobius (not sure about RunCam HD2…) and its base is only 42x32mm. So it can be installed on small frames like 220. But, it will also fit bigger. No problems here.

The best way to install it on a frame is to use either zip ties or double sided velcro straps. There is a slot for 20mm wide velcro straps. To make it better, use 3M Dual Lock between.

To securely install camera also use 3M Dual Lock and use a velcro strap too. That should keep everything in place just fine.

How to print PLA on glass?

When I got my first 3D Printer (Malyan M150) and got into 3D printing I was surprised how consumer not-ready technology this is. Sticking, not sticking, overextrusion, underextrusion, Kepton, blue painters tape, clogged extruder… Over the time, at least, I was able to get the whole 3D Printing process somehow repeatable. I think one of the most important changes I’ve made in my 3D Printing experience is to ditch Kepton and blue painters tape in favor of printing PLA on heated glass. Process got simpler, faster and with better results. Also, not counting initial investment, cheaper.

Flight controller 30.5mm to 45mm mount adapter

Almost all “racing” MultiWii derivatives flight controllers like Naze32, SPRacingF3, CC3D or Sparky, besides the same CPU family (STM32) and ability to run Cleanflight, share the same form factor: 36x36mm size and 30.5mm hole spacing.

That creates a small problem when mounting them to some bigger frames designed to fit APM, Pixhawk or MultiWii. They do not fit and require additional adapters.

Facing problem like this, I’ve designed simple 3D Printed 30.5mm to 45mm flight controller adapter.

To use, 4 hexagonal nylon M3 standoffs have to be glued into place. M3 thread is rather too small to print on most 3D printers. It’s just faster and simpler to glue standoffs than try to print threaded holes. I used epoxy glue, but hot glue also can be used if needed.
