Update 2024: This has several design flaws and does not work as originally intended. A significantly improved version of this is available on Makerworld here: https://makerworld.com/en/models/676508

Adjustable spacers for when your kitchen drawer organizer is too long and your utensils keep sliding too far back. Sketchup file is included so you can easily make the base/backstop whatever size you need.

Update 3/22 After using these for quite a while I've discovered that they actually tend to retract over time. As heavy silverware repeatedly is pushed into them when a drawer opens and closes the locking mechanism repeatedly slips into the next notch. I still find them to be better than nothing, but there may be better designs out there. Maybe someday I'll revisit this one and try to come up with a better locking mechanism.

V2 (update 8/30/21)

New STL files start with "v2".

The original design was prone to breaking due to the vertical print orientation. V2 splits the large flat backstops (bases) from the arms, and the arms have been slightly modified to accommodate printing horizontally for vastly improved tensile strength.

Print your v2 parts in the orientation shown in the second image. They are pre-supported (see the last image for which supports to remove). Print at a 0.2mm layer height or they probably won't fit together correctly.

Arm A should fit tightly into Base A, and Arm B should tightly fit into Base B (long and short versions use the same bases). You will still need to add a dab of superglue to keep the arms connected to their bases.

V1:

Each spacer has 2 parts, marked "pt1" (outer) and "pt2" (inner). Two length sets are included as stl files.

• Standard: ~5.5 - 9.5cm
• Long: ~7.5 - 13.5cm

Sketchup file included so you can easily modify the lengths and the size of the backstops to meet your needs.

Squeeze the tabs on the inner slider to fit it into the outer part and slide it all the way back.Tabs must be squeezed to allow it to move backwards (shorten). It will slide forward (extend) just by pulling on it.

This was inspired by Dauler's adjustable drawer spacer, but designed entirely from scratch. The main benefit of this design over that one is that you don't need any extra hardware.

Printing notes

V2

Print parts in the orientation shown in the second image. Follow the same post-processing stuff described in the v1 instructions below.

V1

Both parts should be printed vertically (large flat parts on bed). I tried printing them horizontally but the slider wouldn't lock- though it might work if you did that at a higher resolution.

All parts have built-in supports for printing in vertical orientation (one turns overhangs into a short bridge), so no slicer supports are needed. These built-in supports are marked in one of the pictures and should be trimmed off after printing.

You'll probably need to briefly take a file/sandpaper to areas where you trim off the supports, they usually leave small burs that are large enough to get in the way of smooth sliding.
