In current version the screw Connectors and the clip hooks of the cover are improved. Rounded edges gives more stability. Printed good on an Ender 3 V2. in freecad you can find the source files, if you just interested to print, choose the stl folder to download. Any critic, improvement suggestion is welcome. This is my second freecad work, would apreciate to get more input from you.
At this point many thanks to flowwies channel! https://www.youtube.com/channel/UCyGwIx_PzM_zE3FKhZRbygQ
