I want to have my own version of hexscraper. So here it is.:

1. Shape and Geometry: I'll keep the basic scraper form and hexagonal design that fits precisely, especially under the blade.
2. Ribs for Better Grip: I’ll add ergonomic side ribs along the handle to ensure a solid grip, making it more comfortable and secure.
3. 0.4mm FDM Compatibility: We’ll maintain the dimensions optimized for 0.4 mm nozzle printing, so the ribs and scraper don’t interfere with the FDM printer's typical resolution, first layer 0,1 recommended for better scrapping :)
4. Minimal Complexity: It should remain simple enough for an easy and quick print.

Bonus: take the scrapper with you all the time as a small version for your keys. Watch for sharp angles. IT SCRAPES! :D

Are you looking for any specific measurements or adjustments to the handle size, or should I go for a general, ergonomic handle fit? let me know.
