Toilet-Roll-Holder

We just needed a holder for our toilet-roll, we actually lived without any for years now (I never wasted a thought about that).
But as enough is enough I made a simple design in Fusion 360 and printed it directly, so in less than a day we had a toilet-roll-holder. I made it in a colourfull design, but of course: pick your own colours.
I glued it to our sink using silicone-mass (so I didn't need any holes), but I provide a variant with 4 countersink-holes for M4-screws.
