MOD-t cover handle inserts

This is an insert for the handle holes of the [NewMatter MOD-t](https://store.newmatter.com/#!/mod-t-3d-printer) acrylic cover. When installed, the fan noise is dramatically reduced.

Print two at 0.20mm layer height and 10% infill for best results.

Printed on one of my finely tuned Mini Kossel linear delta printers these are a perfect snap fit.

Printed on the (closed source) un-tunable MOD-t they come out a bit larger. But, they will still work because they are tapered.

**Update:** Have added a shallower version which will print faster and seems more than sufficient. In the picture of the two shallow parts, red is printed on a Mini Kossel, orange on MOD-t.

**IMPORTANT NOTE:** Please be careful when trying to insert these parts in to the MOD-t case holes as you might crack the acrylic. You shouldn't have to force them in, they should snap in pretty easily if they printed properly. I will upload modified versions for printing on the MOD-t itself as soon as I've tested the
