I designed this mount to install an Omegon Crayford focuser on my skywatcher heritage 150p but it should actually work with any Newtonian telescope up to about 8" or so aperture.

Print in black fillament, suggest a 0.4mm layer height. To print in one piece you need quite a tall printer (like the sidewinder X2) but it could possibly be split and printed in two parts then glued together.

This fits inside the tube of the telescope, can be attached with some cable-ties (or drill some hole sin the spider holder and use screws). Slides in when the scope is collapsed and blocks stray light when it's in use.

I modified LTek's excellent 5020 fan duct for the sidewinder X2 by just adding an attachment point for an aftermarket bltouch/crtouch upgrade.

This is because while compatible with the stock bed level sensor, and after-market upgrade bumps into the fan in it's default position, with this modification that problem is avoided by mounting the sensor directly to the duct outside the space needed for the fan.
