Summary:

Double Hotend fix for Prusa Dual hotend support for Printer Prusa I3 with bowden. 

• New version, lock with rounded corners.
• Made for object: http://www.thingiverse.com/thing:990595
• Made in OpenSCAD, you can change all. 

Instructions:

Maybe you need adjust the OpenSCAD file for your hotend and create a new STL file. 

I see lots of different hotend sizes but it will fit in:

• Hotend - 16mm diameter x 5mm height base and 12mm neck. 
• Hotend - 16mm diameter x 5mm height base and 10mm neck.

You can just cut out 5mm in the hotend base or use bigger screws if you have space in case:

• Hotend - 16mm diameter x 10mm height base and 12mm neck. 
• Hotend - 16mm diameter x 10mm height base and 10mm neck.

Attention: 

The distance between the centers of the hotends is 30mm. 

My hotends have 22mm in the head + cables and screws. 

I believe you will not have problems until 25mm in the head. That is all.

The OpenSCAD file is just here, you can change all.
