The Matrix - Sentinel

In July 2017 I got my Felix 3.1 single head printer. With no 3-D skills or experience I started to make the sentinel. I have read a lot and collect a hole of stl files. After some printing test with stl files I understand de difficult of my printer. Head-temperature/Bed-temperature, Bed-level, Extruder-distance.

I found a sentinel object of Reg Taylor (https://www.myminifactory.com/object/matrix-sentinel-fully-articulated-model-4547) But this was not conform my Sentinel, so I look further. Then I found another Sentinel made by Othon Reynoso (Download no longer available).

This body was better, but not suitable for 3-D printing. I have 25 years+ experience with Adobe software, but I have no skills in 3-D. With a lot of help on You-Tube, I could correct the body, so Simplify 3D can handle it. The body was made for animations and games, not for 3-D printing.

It took me 1.5 months to correct the hole body, so it was watertight.

Then I have scaled the parts from Reg Taylor to my body and make some cosmetic changes (claws and communication disk).

The base plate I have made by myself and took me about 3 weeks to fulfil.

The most parts are printed in 0.2 mm without draft and support.

The smaller parts, like de hooks on his belly, are printed in 0.1 mm with draft end support. This parts are very difficult to print. FILAMENT:

Everything is printed in PETG The grey filament is blue/grey (2.0 kg) https://www.123-3d.nl/REAL-filament-grijs-blauw-1-75-mm-PETG-1-kg-i1556-t7388.html

The Blue/grey filament is painted with Smoke back-light painted (black) https://www.nonpaints.com/nl/motip-backlight-spray-spuitbus-400ml-transparant?gclid=Cj0KCQiA-ebSBRC8ARIsAGuxJIr55rZpHMukB-r2xau107KZEVcNvUSCgwQ3AuuVHRL5Mn45DtoJ85caAnXSEALw_wcB

The silver parts are done (by hand) with Silver-paint from Tamiya X-11 (works great!) These parts are stored in the folders Silver. I have painted them, because the colour of the paint is brighter than the (silver) filament. With zero experience and this creation in five months is for me a milestone :) Software: Blender 3-D Software: Simplify 3-D 3-D Printer: Felix 3.1 Building time: 4.5 months. Printing time: 370 hours+ Total parts: 1220 Size: 40 cm wide - 70 cm deep - 60 cm heigh If there are questions about the purpose of some parts, let me know! SPECIAL ANNOUNCEMENT 1) By printing the body. I have make the construction so that this part can be printed with minimum support. Look at the bevel in the inside of the body to position it right on the print-bed. The only support you need is by the rings where the arms come. The example is up-side-down (wrong side up).

Head: 10 hours printing Body: 42 hours printing Back: 10 hours printing. Arm part red and grey: 200 hours printing

2) I have put one extra picture and two stl files on the site, how I mounted the Sentinel to the body. I hope I can explane the idea whit the images. The lighting of the arms are shut off in this picture to make a clearer site. The small tubes on the left are the power supply for the El-wire and the 12 volt of the LED. The small tube on the right is (extra) the communication pin who connect Neo with the Matrix. The thick tube is the one I am talking about. This one goes from the base wit a twirl over the full colour plate to the belly of the Sentinel. In this tube there is a iron rod. So the total weight of the Sentinel is steady. To keep the Sentinel in position without flipping over I made two extra tube parts. These two part go trough de full colour plate and will be locked by a pin on the other side of the full colour plate. This way it is impossible that the sentinel can flip to the left of the right side.

3) The claw hinge-pins are made from 1.7 mm filament (8 mm long). Moulded together with a solder (flat blade). Use a wooden block with a little hole (2 mm) on the edge. So you can use pressure to the pin to flatten it. Greetings Albert
