Pipe Insulation / Lagging Cutting Jig

With this jig you're able to cut insulation made from PE or PU in 45° angles. The model in the picture is made for 50mm insulations, although it looks a bit wide (the insulation seems to be smaller than indicated). But I also added versions for 15, 22, 28, 44 and 56mm outer diameter. I added a slot in the middle so the jig can be slightly compressed or stretched to match also minor size variations.

I printed it with PETG in 0,2mm structural IS preset. No supports required if printed vertically:

Update 22.03.2024:

As requested in the comments I added a version without the middle slot. Also added 15mm version.
