Artitec & Marklin heavy load car tank securing aid H0 scale

Securing aid to keep tank models & car models from sliding off heavy load cars while going around a MRR layout.

Not too prototypical, but on the other hand very effective. I used to have the problem that the cars & tanks would slide off after running for a while, causing big derailments from time to time. With these small securing aid the tanks sit very tight on the flatcars, they dont even move after emergency braking.

No glue required, the tanks models can still easily be interchanged or removed. Mounting uses the holes & extrusions present on the cars.

I included following securing aids:

• marklin_ssyms_securing_23mm.stl/marklin_ssyms_securing_23mm_nocutout.stl: for Marklin 6-axle heavy load car such as #4867. The version with the cutout supports the included mounting mechanism reproduction (i used only those originally)
• artitec_ssyms_securing_23mm.stl; for Artitec 6-axle heavy load cars such as 20.320.xx series
• artitec_ssy45_securing_23mm.stl: for Artitec 4-axle heavy load cars such as 20.280.xx, 20.281.xx, 20.282.xx, 20.283.xx, ...
  -artitec_ommrlinz_23mm.stl/artitec_ommrlinz_17mm.stl/artitec_ommrlinz_16mm.stl/artitec_ommrlinz_13mm.stl: for Artitec/Roco 2-axle heavy load car such as 20.332.xx.

Use the 23mm size for most tank models. (TIP: I used the great tank models from m_bergman https://www.thingiverse.com/thing:769137 on some of the picture. Scale to ~115% before slicing to get ~H0 scale, the German models will fit perfectly on the 23mm width holders)

The smaller width securing aids for the 2-axle cars can be used for various car & halftrack models.
