Anet A6 A8 Y-Axis GT2 Belt Holder (customizable / parameterized)

An Y-Axis GT2 belt holder suitable for the heat bed frame holder from Bohrers Shop ( https://shop.bohrers.de/heat-bed-holder-anet-a8-und-a6-kommt-in-kuerze.html ) but it should also fit on the stock Anet H-frame (the holes do) and definitely on other holders / frames due to the parameterized making of (after customizing it with FreeCAD of course).

In this heat bed holder the distance from bed holder to the upper side of the belt is 8mm.

v2 is a version for sink screws.

A new (third) version added because my first design does not fit at all in / with this Y-Axis rework solution here: https://www.thingiverse.com/thing:2477814 . On the end positions and if the locknuts have the corners facing up, the max. free space there (between belt holder and locknuts) is only 5mm. It is a very tight design and I am not sure yet of its advantages..

The holes of this thing would not fit in the stock heat bed holder. It is designed to fit in the above holder from Bohrers-Shop. The holes there look like the "blueprint" on the last image attached here. Not yet tested this new design. Update Now, the new design installed and it works / fits! Take a look: https://www.thingiverse.com/make:492501

I have also uploaded the parameterized FreeCad 0.17 files.

Print Settings

Printer:

Anet A8

Rafts: No

Supports:

No

Resolution: 0.2mm

Infill:

50% (Rectlinear)

Notes:

Must be rotated by 90° on X-Axis to print (as shown on the FreeCad screenshot).

I would use 4 layers / perimeters for all. The third design (Bohrers / Y-Axis-Rework solution) needs supports, on the build plate only.

How I Designed This

Used FreeCAD 0.17 to design this thing and tried to parameterize all important sizes / dimensions to make it easy changeable and suitable for many use cases. There are four main sketches that define the most important parts (see screenshots). Uses mirroring for the main belt holder and the holes.
