I needed to cut holes for speakers but also to carve notch for speaker edge to fit in. As I did not have proper tool for that job I had to make it on my own. As I already had cutting guide adapter for my Proxxon grinder I decided to make an adapter for it using 3D printer. It was actually adapter for Dremel tool with customization to fit Proxxon, so new tool may be used with both Proxxon and Dremel grinders.
I did modeling in FreeCAD and printed it on my Prusa MK3S 3D printer. It did a job surprisingly well.
Tool consists of these 3D printed parts:
– body,
– sliding bolts (3 pieces),
– nut caps (3 pieces) and
– needle holders (as much as you need).
Other than that you would need:
– Cutting guide adapter (eBay example)
– M6 nuts (3 pieces),
– M6 Serrated lock washers (3 pieces) and
– something to be used as needles (nails, strong thin wire, tube or something similar) size that fits your needs.
If you have to just to cut fixed radius it is simple to use this tool. All you have to do is to have needle fixed at appropriate position matching needed radius. Tool is then rotated until cut is done.
You can also do notches wider than cutting tool by using limiters. Limiters are actually needle sliders but without needles. So, you should have three needle sliders inserted in slot, with needle inserted in the middle slider. Other two sliders would serve as limiters.

Print using PETG with at least four vertical, top and bottom horizontal shells and at least 60% infill. More infill the better.
Positon parts exactly as in STL. Supports are not needed and not wanted as you need as smooth sliding surfaces as you can get.
