Please allow a tolerance of +/- 1MM.
Please select the external height, width and depth of the case along with the thickness of the clear/coloured acrylic to be used; Please be sure to allow for the thickness of material when working out the dimensions of your case.
All Plinths will lose the thickness of the material from the internal height, and double the thickness from the internal width/depth (depending on the thickness chosen). For example, if ordering a 3MM Plinth, you will need to add at least 6MM to your required internal dimensions to allow for your external. With a 4MM Plinth you need to add at least 8MM to your internal dimensions to allow for your external, and so on.
Please note - Plinths will not be provided with bases; the 'acrylic colour' selected will be for the plinth itself, not for a base; if you would like to purchase a case with a base, please use the link attached here - https://www.puffinplastics.co.uk/pages/case-calculator?gclid=EAIaIQobChMI0f-m0oXg8QIVw-3tCh2q1wurEAAYASAAEgJGP_D_BwE
