Original idea by robert “RB” björkén 

https://www.crealitycloud.com/model-detail/lidriser-modification-creality-k1-max-4-corners?source=26

Didnt like the overall fit of the riser so i re designed it from scratch to my liking

Now everything locks firmly in place after sliding the acrylic panels down and also made the corners a bit thicker for better durability.

I also added a corner with a hole for a threded insert to pass bowden tube through, and just flip that part if you want another orientation

Made for 3mm acrylic sheets with dimensions 305x39mm, theres also a printable sheet with the model

Printed with supports
