I recently found an item at my local crafts store called “the hobby holster”. It is a silicone holster that grips to any surface is relatively smooth, and has a pocket to store things within a convenient reaching distance.
It’s great for keeping things used often with the GF like calipers, Sharpie markers, bed pins, magnets, tape or whatever else you should prefer to use as hold downs for the laser bed. Some have rulers on the portion that lays flat, and it won’t scratch or mar the glass. I used the Michael’s coupons that always available and I paid less than $15.00 for three different sizes/styles. Here are 2 of them on my GF,
(one is on my computer desk, holding my Surface Pro Dial and Mouse. I chose all grey, but they come in several colors. I’ve seen them on Amazon as well, but more expensive.
