Another different type of Holder that can be use on a garage door that lift up for a Festool, Makita or Bosch or Powertec track saw rails... not sure if it would work for other brands like Wen, Dewalt, Milwaukee since I do not know their size... but if same width and height, could also be used...

I like this one since it secures the rail better and to use the back of a garage door that lift up as a "loss "realastate" space", it's PERFECT !!

I recommend PETG since in a garage, often temperatures gets either very hot or very cold... plus less brittle than PLA !

3 walls with an infill of 10% honeycomb should be strong enough!

Supports recommendated by 3DDIY: **should only be used selectively over the hook portion of the holder. If used everywhere the print in place cam will be fused together and not turn.

Here are his Recommendations:

This is my designed version of the Fastcap Rail holder. This has a a design where the cam is print in place. So no extra hardware is needed to set up the lock. This should fit most track saw rails. Kreg and Bosch will need some editing to make those rails fit. You can divide the model in two or try to transform only the bottom half where the hook is.

NOTE: When the print is finished the knob will be slightly fused. You can use a utility blade or a thin screw driver to insert in between and slightly cut and create space by just inserting in.

Update: An additional file is added for anyone with tracks that are fitting tight. This new file has an extra 2mm of spacing added. Also it has come to my attention that if the print is printed on it side it can be easier for some with the cam to be loose. You can print with supports in this orientation. But I would do from build plate only.

Update 2: A smaller Bosch version was added. I do not have a Bosch rail this was done with found specs. If you have a Bosch rail let me know the correct measurements and how this fits. Thanks

Update 3: Added Holder for larger Bosch professional Rail FSN Measurements provided by others so not sure of its accuracy.
