STOP STEP FEET SINKING - And make height adjustable

I designed and 3Dprinted these stackable feet for a caravan or motorhome step which serves two purposes.
The first is to avoid the step sinking into soft ground when parked on grass pitches, this is achieved simply by increasing the load area of the step.
The second purpose is to enable the step to be raised a variable amount by stacking one or more of the additional riser plates. The top plate raises the height of the step by approximately 6mm and the two other models are for riser plates which raise an additional 10mm and 20mm respectively.
Peg holes in each of the plates allow a standard tent peg to be pushed through the combined stack for additional stability.
I printed using standard PLA and it seems to hold up to usage fairly well since the majority of the forces are compression. Infill is definitely required, somewhere in the region of 30% seems sufficient but higher densities should increase longevity of the parts.
I’ve used the step with 10mm+20mm stackers to give a combined lift of 36mm. I cannot guarantee the safety of using this model especially if stacked any higher. By using this model you accept full responsibility for the final printed item and any liability for its use.
You can download the model completely free of charge from ThingiVerse by either searching for DTSquared or using the link.-

This is a concept idea so I cannot guarantee its safety or reliability, please take care if you raise the height of your step in any way.

Can you supply these step raisers ?

Unfortunately no I can't as I don't have facilities to manufacture them at scale. If you know of someone that has a 3D printer then the models can be downloaded and printed.
I'm glad you liked the concept though.
