Chilly's Bottle Holder (500ml) Screw + Strap mounting

A simple holder specifically designed for the Chilly's brand 500ml insulated water/drinks bottles. The inside diameter of the holder is 71mm and the max height is 120mm so it probably works for a variety of bottles.

It comes in two flavours; one to be attached with two screws and one to be attached with straps, typically cable-ties/zip-ties. The screw holes are 6mm diameter and 12mm countersink on the inside at 30mm between centres. The strap holes are 3mm wide and 10mm tall so a decent sized cable tie can be used to secure the holder. The strap-version also has a slightly rounded attachment plate so it fits curved surfaces a bit better.

I've printed them in generic PETG on my Prusa i3 Mk3 with supports from the build plate to support the fastener plate. The rounded base needs a bit of filing and sanding to get it looking a bit tidier. With PETG I also find that there are blobs here n' there, easily removed with a file and sand paper.
