HAPE Quadrilla straight line hole dimension 225 mm

The hole dimension 225 mm (measured at the center of the holes) is for the normal lines. It fits on the roundabout and on the curve which is a 1/6 circle. The total dimensions are 269 x 18 x 44 mm.

Attention:

Update 2021-07-12: I made a big mistake: The old version was 5mm too long. Only use this new version of 225mm hole dimension

Update 2021-06-07: Now I have much more experience with blender and I designed the straight line new. Printing time is lower now.

Update 2020-11-27: There are 44 downloads and 1 collection, so I decided that this thing is not any more a Work-In-Progress thing.

Update 2020-07-17: I added a little brick which you can print twice and stick them with superglue. How to stick it on the line have a look at www.thingiverse.com/thing:4125179

Update 2020-02-28: Yes, there was a problem with the hole in the middle. But now the bug is fixed.

Update 2020-02-09: I made some mistakes. The murbles were jumping wenn the flat fillings for the holes were in. I made some smal bevel into the middle where the marbles are rolling.

It would be glad, if someone who printed it, will give a short comment ore can post a make.

I founded a group for the HAPE Quadrilla marble run: https://www.thingiverse.com/groups/hape-quadrilla-marble-run

Have a lot of fun with it.
