Update 1/16/24: Now with sharp angle cuts (65 degrees) for XL and MMU.
A long time ago I discovered pomi's filament cutter but wouldn't want to use it without a box a la wapameeto's. Over the years, I have modified this system a bit more, to make it more robust, versatile, and easier to use.
To complement the standard 45 degree cut option, I added one for 65 degree cuts. I found that feeding my XL and my MMU3 was much easier with a sharper angle cut than the usual 45 degrees.
Included are also several mounting options:
STP file included
Prints fine in PLA, PETG, PCCF. I recommend at least 3 perimeters. 15% gyroid or cubic infill.
3030 versions: Need supports for the 3030 mounting hook; see .3mf files. Careful when you remove the supports—don't shear off the mounting hook. To mount into the extrusion, insert the mounting hook, then rotate by 90 degrees.
Check video instructions here.
1/29/24: Improved box design! I got irritated that the cutter jumped to easily out the front of the box when pressing down, so I changed the box design to make it more secure. While at it, I made quite a few more minor quality-of-life changes. Most significantly, I increased the width of the channels in the body for the screws, so they slide in and out more easily, and I slightly increased the size of slot for the blade in the top, so it's easier to insert the blade.4/18/22: New model with 3030 side mount for Prusa XL
11/8/22: Somehow the cutter body model lost height 🥵 Replaced it with the correct model. Thanks to @mike s. for discovering the problem.
9/20/22: Redesigned the box to make the insides straight, to avoid printing artifacts from the sloping inside walls of the original design. Added 3030 mounting option.
6/17/21: Added option to mount it to your enclosure (or other convenient place) using @layershifter's “multiclip mounting system”. Requires a flat-head wood screw (I used a #8 x ¾).
6/7/21: Regenerated Cutter Body from FreeCad file, to remove artifacts.
