I designed this base to attach a Telrad Finder to a Vixen Finder base.
I have printed it using a Makerbot Replicator+ using 4 shells and a Tinkerine Ditto using 2 shells. I forgot to use 4 shells on the Ditto so we will see how strong it is. At first glance it seems fine. The four shell version has been in use for a few months now and shows a few dents where the attachment screws have been over tightened by overzealous astronomers. I think they err on the side of caution and over tighten because their stuff is expensive and they don't want to be the one who did not tighten it enough resulting in gravity teaching them new lesson. However in this case there is no need to have them anything but finger tight.
- No rafts.
- 0.2mm layer height.
- 2 shells.
- 10% infill.
I attach it using two 10-24 x 1/2" Robertson machine screws just because they were what I had lying about.
The holes for the screws are a tight fit which works well and keep them from coming loose. This was by fluke not by design. :)
I have included the two Replicator files and the Ditto file:
- One Replicator file is 2 shells and the other 4 shells.
- The Ditto is 2 shells and if I remember right I made it a lower resolution layer height. Again, it seems great.
