Band saw angle guides

One of my other hobbies is pen making, and for some pen blanks you need to accurately cut angles into the blanks.

I've got a band saw which is quite a generic one available under several brand names, which has a thick guide bar - approx 50mm x 25mm, so have made these guides at 45°, 30° and 60° that sit on the bar and freely slide along, allowing very precise cuts.

The skeletal style reduces filament usage and is actually quite rigid when printed densely, with the angled corners allow for a little less bridging - my Ender 3 has no problems getting across the gap.
