Various HSW add-ons

Race Car Seat Holder
I'm sure you're all familiar with the smartphone stand in the shape of a race car seat.
If not, here's some info: The oldest copy of the seat I found is from 2021, https://www.thingiverse.com/thing:4779381. This one references the original, but the link is dead (404). Then there are other copies and remixes, on Thingiverse (e.g https://www.thingiverse.com/thing:5322693) or here on Printables (e.g. https://www.printables.com/model/106121-car-seat-phone-holder).

Because I had printed the seat and would like to use it for my old smartphone, but didn't want to waste desk space, I created an adapter for the HSW.

Holder for Deburring Tool
I wanted to store my deburring tool on the HSW without all the spare blades that come with it and needed a simple holder that would fit my tool (with a diameter of 13.6 mm). Since I didn't find such a holder here on Printables, I made my own.

Holder for Cutters
There are many such holders for side cutters here on Printables. But I wanted to have one that fits the design of the HSW, i.e. it should have the typical honeycomb shape.

Case for A7 Index Cards (or other things, like my tweezers case)
The case I got my tweezers in was too nice to throw away and just hang the tweezers. I therefore created this holder for myself, making sure that it also fits A7 index cards.

Case for Business Cards
A smaller version of my holder for the index cards, for standard business cards.

Shelf for Filament Boxes
I store my filaments in the boxes they come in. Then I can see at first look which brand I have in front of me.
When I take a filament out of the closet, I put the empty box on one of these shelves and leave it there until I'm done printing and put the filament back in the box and with the box in the closet.
For the purpose, this shelf is 75mm wide, has a flat surface and is relatively solid. It is a remix of the shelf from RostaP.

Holder for A4 Paper Sheets
These holders make it very easy to attach paper sheets to the HSW. They are horizontal holders to hold the paper right and left and vertical ones to support the paper downwards. I created different versions of the holders, some with a straight shape and others that are more oriented to the design of the HSW inserts. In each type I have uploaded three variants, with 3 mm, 5 mm and 7 mm space for the papers.

I used file shelf.step and made one of the included shelves more solid.
I also used that file and insert-empty.step to make some measurements for my own inserts.
