I can only manage to find 16mm x 10mm in coiled pvc from RS Components catalog. Not much different from the 1/2" version (20mm x 10mm) from hardware store. There is a micro pvc trunking with 7mm x 12mm but available overseas.
Does anyone know where to get the micro pvc trunking? The hardware shop only have the 1/2" pvc trunking. Looking for micro pvc trunking with sub 10mmx10mm or smaller.
