toilet flange extender spacer

a extender for a standard 3" pipe toilet flange, available in .25" and .5" very useful if you lay laminate flooring over linoleum for example, make sure that wax ring is getting squished. i went to buy one but $30 at my local hardware store for a bit of abs seemed crazy when i already had abs in my printer. silicone or use abs glue to seal to your existing toilet flange, i left the cut outs so you can replace the bolts i printed mine out of abs to match the material but if your siliconing in place i cant see why you couldn't use any other filament that's going to be ridged and not break down with water like all DIY plumbing, use at your own risk, thanks
