Summary

This fixing can be used to hold external wall insulation onto your house securely and with far less thermal bridging than other commercial screw solutions.

See here for details of thermal analysis.

Combine it with a 70mm wood/masonry screw and wall plug. Just drill the 7/8mm hole in the foam and masonry at the same time, then push hard and this will slide into the hole and be pulled in by the screw giving a very secure fixing. Designed for 100mm foam, but can be adjusted for other thicknesses.

Print in ABS or PETG - PLA isn't good for long term outdoor use.

Can print in 11 minutes with a 0.3mm nozzle, which is good considering you'll probably be needing ~400 for most projects...
