20/03/25- I noted that Ankermake studio has some foibles when saving/ creating .3mf files using void volumes- for some reason this means that the files created in AM studio are not readable by Prusa slicer (gives an error when loading) so i have added files for the launch panel, cable winder, launch key tag, launch rod cap and launch rail cap that are created in prusa slicer and will therefore open in prusa slicer- these files are labelled ‘prusa’. All other files should load fine in Prusa or, indeed, other slicers.

Model Rocket Launch Controller
