Hello

Sand table are sometime tricky to pimp !

• Correct sand (or backing soda) 
• Correct size of ball ang underlayer magnet
• Magnetic ball !
• Faux leather or other device under the sand…

These parameters are tricky to solve, but one of them is the thickness off the sand layer.

With this comb (the same i use on my models) you can distribute from 1.4 to 2.7 mm of sand on your support

My designs with a 5 mm magnetic ball use the smallest adjustment (number 4) as the picture shows on a pattern.

If needed you can scale the model before printing

My name can be removed, just paint it the same color as the part
