Wrapping Paper Cutter- wrapping paper cutter

Please read the description to the end before downloading! This is a remix and redesign of the "Wrapping Paper Cutter, utility knife 2.0!", https://www.thingiverse.com/thing:5158937. I have a pack of 70mm long carpet knife blades, and I have redesigned the tool to fit them. ** Before downloading and printing, please test whether your blades cut paper well! ** To assemble you need a carpet knife blade 70mm x 19mm x 0.6mm, like this one here: https://grabcad.com/library/carpet-knife-blade-70mm-x-19mm-x-0-6mm-1 and a screw M3, cylinder head screw or flat head screw. For ø50: 12mm long, for ø60: 12 to 16mm long. December 16, 2024: matty82 has requested a cutter with a diameter of 50mm. Here it is. December 19, 2024: Thanks matty82 for his remarks and suggestions. Now I have revised - and hopefully optimized - both sizes, 60mm and the new 50mm diameter. - The blade has moved upwards and a little inwards, twisted so that it is more tangential to the diameter. - some minor optimations for better printing and assembling. - all new models are also available as step and parasolid. - the old, first version is still available in the archive.zip. February 21, 2025: After a request from user ‘schmerzbereiter’ I have added new versions for a 61mm blade. Attention: I don't have such blades and can't test if everything fits and works, I only have the information from schmerzbereiter for the 61mm blade (see comments). To avoid confusion, I have renamed the files and uploaded them all again. Important: Nothing has been changed in the versions with the 70mm blade (except the file name)! File naming system: Papierschneider D xx -Klinge cc mm-partname where: xx = inner diameter, 50mm or 60mm cc = blade length, 61mm or 70mm partname = Part name: "Ring" or "Verschluss"
