Summary

Well, I've discovered yet another Torben Holmbäck Desk Block. This make five. The set also includes a Tape Block (https://www.thingiverse.com/thing:7018881), two different Pencil Blocks (https://www.thingiverse.com/thing:7123447), and the Desk Organizer Block (https://www.thingiverse.com/thing:7123467). I found this one on the Cooper Hewitt, Smithsonian Design Museum website (https://collection.cooperhewitt.org/objects/18648645/). It has 3 slots for holding papers/letters and a circular cutout for paper clips etc. All of the blocks have the same external dimensions (70 x 105 x 42 mm). All of the originals were machined from a block of black anodized aluminum.

I also found a couple of additional Torben Holmbäck objects on the Cooper Hewitt site and will be posting models of those to my Holmbäck collection soon (https://www.thingiverse.com/hjs521/collections/43433241/things).

As with the others, I've added a cavity in the base that allows you to add self-adhesive wheel weights to give it some heft. The cavity is designed to hold these wheel weights (Amazon: https://a.co/d/1S71y2b) in a 3 high stack of 2x2 weights. I haven't printed this yet but will post pictures when complete.
