Adhesive Tape Dispenser
This ultra heavy adhesive tape dispenser gets its weight from a 1kg lead block inside the corpus. I got the lead from eBay as diving accessory. The body is made from 8 layers of 6 mm birch plywood.
The tape is hold by a aluminum tube which I cut to the correct length. It'd be a nice look if the tube is replaced be a complete aluminum or maybe a brass rod.
I got the knife from Opitec, which is a German crafts store. It was inserted into a thin slot that was sawn by a small hacksaw after gluing the inner parts together.
To ensure the tape dispenser doesn't slip I experimented with funky foam and settled with a thin mousepad which I cut to size and fixed with double sided adhesive tape
