I couldn't get the screw-tightened designs from Thingiverse to print perfectly so here it is.
Ξ A simple hobby blade (#11 Xacto) handle for...not-so-perfectly-calibrated printers. Ξ
• Main idea is to use a scrap piece of filament, screw, nail, whatever you want, to hold the blade in the handle. The hole is perfect for the blades I use but if it doesnt work for you, I uploaded a file of the handle with NO HOLE so you can measure and drill one yourself. I have also uploaded a file of the cap with clearance over the hole in case you want to use a nail or something that isnt perfectly flush with the handle.
• This works very well, I use these everyday in my line of work. This is actually the 17th design that I tested. Actually i tried a 17th design and found the 16th to be best. UGH!
• The cap is a tight fit, that's kinda the point. If you think its too tight, try increasing the cap size to 103% or something in your slicer program. That may or may not work.
• After you get the first blade in, future blade changes will be easy.
***I am not responsible for any harm or damage caused by you to other people or things while using this handle. Don't be stupid. Be careful with blades at all times.
Doesnt matter PLA, ABS, PETG, etc.
Ξ Printing Tips Ξ
• Print with an infill around 30-50% for added strength
• For even more added strength, print with 3 walls thick with an alternating wall between infill layers (in Cura, just search for "alternating" and it will pop up).
• Print somewhat fast to bridge the slot as best as possible. I printed mine at 50mm/s.
• Supports highly discouraged
