Parkside PSS saw guide slack eliminating adapter.

I have recently bought the Parkside PSS rail saw guide and I had problems making long straight cut with it due to a slack in the internal slider. When I fied the guide, pushing with not much force from the side would move the guide for upto 1mm.

I have found that the slider doesn't perfectly fit the guide's rails. There is about 0.5mm slack. And the internal part of the slider is almost 5 mm far from the internal walls. 
So I have designed this adapter that easily slips over the internal part of the slider as you can see in one of the photos. It gently touches the internal walls and eliminates the slack.

To install the adapter, you need to take the guide apart. The lever has a pin in it. At one end, the pin has “teeth”. You need to push it out so that the teeth part slides out. Then you can remove the lever and pull out the end cap and the whole rod. 

Then you just clip the adapter on the slider and insert everything back. The little tricky part is the lever reinstallation. You need to pull the rod by the hole out a bit against the force of the spring at its other end and hold it somewhere inside the ruler so that it is not pulled back in. Then putting back the lever and pushing the pin back finishes the installation.

I recommend using printing it with PETG, 0.2mm layer height.
