Foamboard Hole Reinforcements

thingiverse

Have a foamboard model that you want to reinforce or repair a hole on? Maybe you want to have a pivot running through the foamboard and need a grommet to keep from wearing out the foamboard and want to distribute the load out more evenly. Here you go! Designed these for a canard pivot and figured maybe others could use them for other purposes. Steering pivot, Wing attachment points, Screw points, Thread them, drill them, have at it! Four hole sizes for either single or double layer foamboard. 1.5, 2, 3, and 4mm holes in 5mm and 10mm lengths. Press fit collar pair can be positioned collar in or out. Use glue for secure hold.
