I have been searching for a simple riser for my X1C, no light, simple, fast and easy to print. Found the design by krazyderek, and I added Ø6x3mm magnets to improve the hold on the X1C metal frame. The original designer allows remixes, so don't go report license infringement before doing due diligence. I have also included these step files of my remix.
Ø6x3mm magnets - 14pcs (18pcs optional)
As with all my designs, Prototyping and testing were conducted to ensure printability and meet my own expectations. However, I understand it may and may not work for you. I would request that you read all instructions and print and install them at your own discretion.
