Two kind of hammers for kicking the marbles up to speed in your marble run!

The 13mm version uses normal Gravitrax steel balls. The 15mm version uses the larger 15mm steel balls which are also used for the Gravitrax scoop.

I ordered both from Aliexpress (be aware you don't order stainless steel, they don't work with magnets)

Note; this design is ONLY compatible with my 6 exit basic tile. The basic tile is compatible with gravitrax.

You’ll need this part to put the inset in:

If you found this useful, please donate what you think it is worth to my paypal.me. Help cover the time of design.

Thanks, Enjoy!
