Solar Filter Adapter for Anders' Travel Telescope

Attention! ⚠⚠ NEVER POINT THE TELESCOPE AT THE SUN ⚠⚠ without protective measures: a good certified solar filter securely attached; a full-length light shroud. Direct sunlight should have NO WAY inside the telescope. ⚠⚠ Risk of severe damage to the eyes ⚠⚠ - and not just yours! And DO NOT USE PLA for this model! PETG or other high-temp and UV-resistant materials should be used instead. If you're planning solar observing - ATTACH THE SOLAR FILTER BEFORE TAKING THE SCOPE OUTSIDE. And when you're done observing - FIRST TAKE THE SCOPE INSIDE, and only then remove the solar filter. Description This is an adapter for an off-the-shelf solar filter that is 155mm in diameter or more - for example, SVBONY SV229 Solar Filter. It is intended for the Anders' Travel Telescope If you want to have this adapter as a permanent addition to the telescope (which is what I did) you can also print a protective lid and a Bahtinov mask from my other model - they will fit the same. Instructions You will need one M5 or M6 heat insert and corresponding thumbscrew that's at least 15mm long. Original model by @Xypris is designed for M5, but I've used M6 with a little cleanup - in this case it's important to not push the insert too deep, so that it doesn't stick inside the part. Do not use PLA! It can melt in the sun and make the attachement unsafe! I recommend printing main body and the inserts in black. Don't use high infill or many walls - the part has quite a big volume but doesn't need to be very strong. Print 3 inserts. Inserts should be glued into the corresponding slots of the main body. There is an aiming assist that I've extracted from the original model - a rod and a target. Target is a little circle that should be printed in white and glued on top of the hole for the rod. The rod I've printed with XY-contour compensation of -0.15 and it fits the hole very tightly, but you will probably need to do some trial and error before getting it right with your printer. It's important that the rod prints well, is very straight and doesn't wobble at all.
