the main mechanism is my old modded shengshou 6x6x6. the attached pieces are 3D printed and glued to the puzzle. printing took 2 days, glueing 1 day, but sanding and adjusting a whole week.
the tensioning was really loose, but Iactually fixed that after the solve so this shouldn't happen anymore.
Stickers will defenitly help, but I'm not sure what color I should get yet ^^
