Knob, Handle for Lohberger ovens

This is a replacement knob for a Lohberger oven. The original knob shattered and is quite expensive from the manufacturer. This Knob fits quite a few ovens from that manufacturer I guess - it's for a ZEH 55.3 in this case. 

I added the model of the flange which fits on the metal prongs, so you can design your own handle around the flange. To remove and install the handle, just bend the metal prongs. 

The knob I designed has an access hole which can be plugged with the included plug and a 19mm hex socket. My design has flaws, the threads don't start easy, so you may need to post process the thread start. 

For material choice I printed it in PLA. The knobs actually don't get hot and since this for the air door, it will be absolutely fine heat-wise.

This model designed using Fusion 360. (hence the data format of the flange)
