About this 3D model

Most of the designs already available were complicated or too large for my application so decided to create my own. Simple design intended to be used with 25mm uPVC pipe. This is a metric measurement and not imperial. We're in the 21st century here in the UK! The 25mm pipe I purchased from Screwfix measured 24.75mm in diameter. The print has 25mm holes allowing for a snug push fit. Should be self explanatory. I cut 40cm lengths of pipe which accommodates 5 spools. Fusion 360 files also uploaded if anyone wishes to alter the pipe size.
