Geocache Container for 95mm Logbook with Drawer

Compact Geocache container for standard logbook in format 95 × 16 × 3 mm with drawers. This variant is specifically designed not to open by shaking or tilting.

Design

• Compact design for small and hidden places
• Integrated drawer (slider mechanism)

Function / Access

• Opening not directly visible

• Access only via a small opening with
  e.g., nail, wire, or thin pen, if you don't have one with you, you'll have to come back :))

   

Magnet system

• The container itself is not magnetic
• However, I designed a base so that it can be flexibly used for your magnets; I will upload it without holes or only with my 16x4 mm rounds, so you can create your own holes in the slicer by adding a negative part.

Interior

• Suitable for logbook 95 × 16 × 3 mm
• Secure fit without rattling
• Protected logbook by internal drawer

Print Notes

• There are two versions, one light version only by tightly clamping the drawer, the second is with 2x5 mm cube magnets
• I designed the file to fit precisely, so it clamps well. Unfortunately, I found that when I used a different PETG, the drawer was so tightly stuck that I could only get it out “too” difficultly.
• If this happens to you, there is a way to simply file down the back of the drawer a bit (simplest variant)
• The second variant is that you print a different housing; in the profiles, there are two more, one with less (tensioner thickness), v2 has no (tensioner) which I used when printing with PETG Carbon because the drawer was already tight enough there, v3 has the (tensioner) at 0.1 if the “original” version is too tight.
• In the main print profile, I have the version that I designed with 1 tenth precision; this fit best with my Marble PETG.
• In the variant with the magnets at the end, no tensioner is provided or necessary because the magnets hold the drawer, so if you have 2x 5mm cube magnets available, print this variant.
• In any case, a 0.4x4x12-15mm spring is required
• Basically, I also recommend printing with ABS and ASA, but due to the strict tolerances, I have not yet tried these filaments, as different PETG variants already caused problems :) so I didn't need that many :)

• Material: PETG, ASA or ABS, as PLA is not weather-resistant

   

Notes

• Mechanics dependent on print tolerances → may require slight post-processing
• Individual embossing (text/logo) possible upon request

Assembly of the drawers It was important to me that the drawer doesn't get lost etc., so I designed it with two “noses” that hold the drawer in the housing.

If it's not important to you, you can also omit it; I will provide a profile without it

Assembly without magnets (if you chose the magnet variant, you absolutely must observe points 2a and 2b) since the drawer cannot be removed once the noses are in.

1. After printing, check if the pins (noses) are smooth-running by trying from the outside

2. Then check if the drawer is easy to remove; if it's too tight, lightly file it down as described above or choose another housing variant

2a. Glue the magnet into the drawer (let it dry for a long time)

2b. Place the magnet on the drawer magnet, apply a little glue, and slide in the drawer, wait a bit.. (I would then remove the drawer again for now; if the magnet stays in, all good, and you can proceed with step 3)

3. Inserting the pins on the left and right is a bit fiddly, but what wouldn't you do for a great cache.

4. Insert the spring into one side, then press together and thread it into the other side, preferably holding it with your thumb so it doesn't spring away.

I would be happy if you have as much fun with this as I do, and I hope for pictures of how you craft or deploy the cache.

Important:

I have tried my best to describe everything, create profiles, etc., however, a mistake might have occurred, please let me know if you notice anything.
