Only difference with the original design is the larger screwdriver slot. Top part is 20mm diameter by 90mm long. Followed by a 10mm diameter, 62mm long space for the tip.
Printed in PLA at 0.3mm layer height with 0.6mm nozzle. It works but the bit slots are a bit too tight. Maybe 0.2 height gives better results.
The author remixed this model.
