I made these holders because I can't open the tophat completely where my V0.2R1 stands but still want to keep it open sometimes. These fit loosely but securely into the stock printed parts and the extrusions under the tophat in the back of the printer and hold the tophat at a 35 ° angle. They are aligned with the extrusions to prevent them from rotating.
I hope someone finds them as useful as I do.
The step-file is a single holder directly exported from FreeCAD and the obj-file are two holders in printing orientation as you need one for each corner in the back.
This is my 4th or 5th iteration of this part and it could be optimized further.
Update: Now the FreeCAD-file is included so you can easily modify the part.
