Playseat Challenge Shifter (TH8A) and Handbrake (Moza HBP) mount

This model was inspired by the design of DonKeulito. I needed to re-design the model as my angle of the tube it attaches to did have a different angle and I needed it for a different handbrake and shifter. The chair can still be folded with the mount, but it will close a few milimeters less than without it (I needed a little mit longer strap to keep it closed). This is designed for my chair, with my inclination of a little bit above 45°. Please make sure to measure the angle of the tube this is mounted to, before wasting a lot of filament on it! 

I provide all my models for free, if you want to support my work, you can buy me a coffee!

This model is supposed to be used with the Moza HBP handbrake and the Thrustmaster TH8A shifter. The model can be printed with minimal support, but it still requires a large amount of filament because of its size and the strength requirements. The mount is attached to the tube with 7 M6x40 screws with conical head. Additionally I added 3M VHB tape to the tube before adding the mount, to prevent any twisting or slipping of the mount.

The print process requires some manual work as 7 M6 nuts must be inserted while its printing. I recommand to add pauses at the relevant layers (the provided *.3mf already contains the pauses). The Moza HBP and the shifter can be attached to the mount with M6x35 screws with flat hat.

My own review of the design:
Before I used the mount from jeoje to just mount the TH8A and it worked fine, but it had quite some flex and I could not mount the handbrake. Also for me the shifter was positioned just to far away. Afterwards I did a remix of the mount from frez_knee, but this showed to be just to weak to really support the handbrake and it broke in the first test. That is the reason I tried to redesign the design of DonKeulito, but I had problems adapting the model because of my differnet angles and at the end a complete re-design was easier for me. I also made it even sturdier by reinforcing it and adapted the design to reduce the required amount of support material. My design has some drawbacks:
- The shifter is relativly close to the handbrake, if you grab it from the top, you might pinch your fingers, it might be better to move it out a cm to the outside. 
The handbrake is in the direkt path from the wheel to the shifter, it would be better to move it a bit further to the front of the chair or the shifter a bit more to the backside

Additional mounting hardware required:
- 7x M6x40 screws with conical head
- 7x M6x35 with flat head
- 9x M6 (safety) nuts
- 4x Washer
- Double sided tape (e.g. 3M VHB)
