Giá Giữ Vít (Screw Holder)

This is a remix of a model by @LoboCNC. The original screw holder is quite universal: it fits many hand screwdrivers as well as standard hexagonal bits.

My problem was that I have some short hexagonal bits that I still wanted to use but the standard round extender they fit into was too big for the original screw holder.

This model is slightly larger than the original. Just making a round hole left walls that were way too thin.

You don't have to choose one of them: print both and all your needs will be addressed .

Printing:

• Print flat as it lies in the pictures. 
• No supports are needed even if your printer doesn't bridge too well. 
• As per original suggestion, PLA works perfectly. PETG should too.
