AM8 Z-Stop and Bling

thingiverse

This is a small addition to the Pheneeny metal frame upgrade for the Anet A8, commonly known as the AM8. I have been highly impressed by the improvements the metal frame concept has brought. I decided to add a few things, one being some bling to make it look even more handsome than before. Attach it with double-sided tape. There are two versions of the Z-Stop switch mount available. I suspected that the simple bar printed in PLA was flexing too much. ABS would be a better choice. However, I designed a more rigid mount with three lots of holes to fine-tune where the switch is placed. This is essentially a very coarse adjustment, to be combined with a screw for the final fine adjustment. I have now printed the fan-badge bling. I was going to spray it black and sand back the "AM8" to make it stand out, but chose to highlight the lettering with a black Sharpie instead. The font used was "Magneto Bold," which can be found on Fontzone.net (https://fontzone.net/font-details/magneto-bold). The AM8 - Metal Frame for Anet A8 project by Pheneeny is available on Thingiverse (https://www.thingiverse.com/thing:2263216). My recommendation is to avoid using the "T" type nuts that can be inserted along the 20-20 gap and turned to fasten them. These quickly become infuriating, and I preferred buying wedge-shaped nuts (T Nut Square Solid Slide in Tee Slot) instead. Loosening bolts to allow final alignments and squaring up was greatly facilitated by using the wedge-shaped nuts, as they do not twist and release like the others do (usually in hard-to-reach places!). Other people's projects used include: I used the Z-Stop adjuster from https://www.thingiverse.com/thing:2703393 on the previous A8 and designed a simple L plate to be used with the X-Axis adjuster from Babarikado's design (black, see photos). I found using a Biro spring and an ordinary nut worked well, and a nylon-nut is not essential. I have also added a small 5-sided knob to the Z-Stop adjuster screw. The screw thread has a pitch of 0.5mm, so each facet on the knob is equal to 0.1mm.
