Hey guys.
I use a Jobo 7451 enlarger (known as LPL 74500 II outside Europe). I bought it a few years ago used and it only came with the glass carrier for 4x5 negatives. I used black paper to mask 35mm and 120 film negatives but that really was cumbersome.
Since about a year I also have a 3d printer in my basement (Creality Ender 5 pro) and decided that I will make my own carrier. I took all measures of the 4x5 carrier and made a design in Fusion 360. It is adjustable for all film sizes, I personally have printed it for 35 mm (24x36), 6x6 and 6x7 by now. Works perfectly

If any of you owns a Jobo / LPL / Saunders 4x5 enlarger and needs some negative carriers and has access to a 3d printer you can download them at thingiverse.com (you need to be logged in for the link to work, otherwise you will see a 404 fault):
Since new film carriers for my Hobo 7451 are not available anymore in Germany and ordering from the only remaining provider in Canada is quite costly, I made my own film carrier for 35 mm film and 120 film. I use the 58.0x58.0 carrier for square medium format and usually 36.4x24.4 for 35 mm...
The filenames give the cutout size. I prepared carriers for 24x36, 24x65 (XPAN), 645, 6x6, 6x7, 6x8 and 6x9. If you need anything else, let me know, it can be adjusted in minutes.
