Underwood Portable Typewriter Ribbon Spool Cap Thingy

My Underwood Portable was missing these thingies, so I went to designing and testfitting until I've arrived at a Version that fit's nicely.

If you need both, remember to mirror one!

Please ignore the absolute mess that is my printers surface quality. He's a senior citizen by 3D-printer standards.

I've included both a version with and without the underwood logo.
(Pro-Tip: - You can put your own logo onto it. Be sure to post a make, if you do. I'd love to see!)
