Railcore II 300ZL/ZLT Updates

October 23, 2020 1 Comment

Last summer we announced the difficult decision to no longer work with ProjectR3D. In that decision we also mentioned that while we were uncertain about our future with the Railcore, we would begin selling them again if we could determine a path forward that also had the blessing of the RailcoreLabs designers.

Well due to popular demand, we are happy announce that we are officially back! As of today, 10/23/2020, we are back to selling full Railcore II 300 ZL and ZLT kits. 

Since last summer, some updates have been made to the design of some parts in our kits. Those updates are listed below.

Railcore II 300 ZL
Updates to physical parts:

 

Side Panels
  • Textured on both sides
  • Offered in black and white
  • Railcore II 300ZL/ZLT logo moved to top of front panel
Printed Parts
  • Non-structural parts are now blue
  • Structural parts are now printed by J. Steve White, co-designer of the Railcore, on his Railcores in carbon fiber filament

  • Wiring is 300v rated, RoHS/REACH compliant, and UL Recognized
