Simple Tablecloth Holder in 3 different versions. Select the version you want to print. Files are marked as v1, v2 and v3-A / v3-B (both needed) as displayed on the image above from left to right.

The .3mf files are pre-configured for PLA and PETG and are labeled accordingly.

Advantages 
Easy to print, no supports needed. The main advantage is, compared to all holders you can buy, that you can scale the Tablecloth Holder in height by using your slicer so that it will fit exactly to your tabletop.
 

Example: If you have a thin glass tabletop simply scale the height down. If you have a thick wooden tabletop simply scale the height up. (s. printing instructions)You can use your preferred material and print in PLA, PETG, ABS a.s.o.. I personally recommend PETG, ABS or ASA.
