Some caravan sites are not level and may be beyond the range of travel of the corner steadies. Rather than carry a number of heavy wood blocks to stick under the corner steady, why not have some light weight, stackable blocks. This design is 25mm tall and can be safely stacked if additional height is needed. The raised centre circle is large enough for the AL-KO Big-Foot™ corner steady feet (as is on my caravan).

Warning: this model only just fits on my printer (235mm x 235mm build plate). I printed it without skirt or brim as it would exceed the build plate.
