Objects

This is a collection of ImplicitCAD files for an assortment of objects. Enjoy! (Note that versions fudged for HacDC's miscalibrated Rostock & compiled .stl files are available for many of these at HacDC in the ImplicitCAD/radioshack_box directory on the renderadmin computer.) box1-box4 are boxes that fit the parts drawers that were used at Radio Shack (sort of; there is so much random variation in the drawers that the boxes are sometimes too loose & sometimes too tight): module box1(BT,FH,H,PL,PB,SW,TT,UL,W,WT,G,cos,sin) /*type 32*/ {difference()/*remove inside & notch*/ {linear_extrude(H)/*make solid*/ polygon/*outside*/([(0,SW+PB+PL*cos/sin),(PL,SW+PB),(PL,SW/2+TT/2),(0,SW/2+TT/2),(0,SW/2-TT/2),(PL,SW/2-TT/2),(PL+SW/2-TT/2,0),(W-PL-SW/2+TT/2,0),(W-PL,SW/2-TT/2),(W,SW/2-TT/2),(W,SW/2+TT/2),(W-PL,SW/2+TT/2),(W-PL,SW+PB),(W,SW+PB+PL*cos/sin)/*back*/,(W,UL-PB-PL*cos/sin),(W-PL-PB*sin/cos+G*sin/cos,UL-G),(PL+PB*sin/cos-G*sin/cos,UL-G),(0,UL-PB-PL*cos/sin)/*front*/]);

dna.txt - Sept. 10, 2019 dnaa.escad, rnaa.escad, etc. print schematic but fairly realistic puzzle piece-like representations of the nucleotides that make up DNA & RNA. They can be printed in various sizes; the standard size (n=1) is very roughly 20 x 25 x 12 mm while double size (n=2) is twice that. The size should not be set below n=1 but can be made as large as can be printed. A standard size piece takes roughly 5 minutes to print making them good demonstration & test objects; print time goes up as roughly the square of the size. The following files have been prepared (all files should be printed with Platform adhesion type=None; all files with built-in support (the support parameters may need to be adjusted individually for different printers) should be printed with Support type=None; all others should be printed with Support type=Touching buildplate unless otherwise stated); the standard .escad files are shown below while the Rf.escad & .stl files are available at HacDC: dnaa -

standard size with support for Rostock ddC2Rf.stl - double size for Rostock Printing the various dnat1Rfs###.gcode files can be used to determine optimum printhead temperature for the current Rostock filament; just compare the print quality of the pieces & use whatever temperature works best. Warning: The pieces are a choking hazard. Nucleic acids are long chains of nucleotides; each piece represents a nucleotide. Nucleotides are made up of a base (the vertical part; adenine, cytosine, guanine, & thymine in DNA; adenine, cytosine, guanine, & uracil in RNA), a sugar (the flat part except for the knob; deoxyribose in DNA, ribose in RNA), & a phosphate (the knob). The base joined to the sugar without the phosphate is known as a nucleoside (deoxyadenosine (dA), deoxycytidine (dC), deoxyguanosine (dG), & thymidine (T) for DNA, adenosine (A), cytidine (C), guanosine (G), & uridine (U) for RNA (yes, adenine & guanine are bases while adenosine & guanosine are nucleosides but inconsistently cytosine is a base while cytidine is a nucleoside)). The nucleotides are called deoxyadenosine monophosphate (dAMP), deoxycytidine monophosphate (dCMP), etc. In DNA & RNA G pairs with C while A pairs with T or U; note how the vertical zig-zags of the bases fit together (DNA & RNA can pair with themselves or each other in largely the same way). DNA stores information and is normally double stranded (the famous double helix). RNA is used to transfer information or is structural and is usually single stranded (with many small double-stranded regions where it pairs with another part of itself). The model correctly shows single-stranded RNA & DNA being more flexible than double-stranded, but is far too rigid in both cases. With these pieces it is possible to explain some features of nucleic acids: It is easy to see how double-stranded DNA can replicate - just separate the two strands and make new strands by selecting the pieces that fit together correctly. Since G pairs with C & A pairs with T double-stranded DNA contains the same amount of G & C and the same amount of A & T (this does not apply to single-stranded nucleic acids (i.e., most RNA)) but the amount of G & C need not be the same as the amount of A & T. Which do you think would be more stable: DNA with a high G & C content or DNA with a high A & T content? Can you figure out why DNA uses T (which takes the cell more raw material to produce) instead of U (hint: C can occasionally degrade to U)? DNA contains the information for producing proteins made up of 20-22 different amino acids strung together in a row (just as DNA is composed of the 4 different nucleotides A, C, G, & T strung together) plus a stop signal. Three consecutive nucleotides in DNA code for 1 amino acid in a protein. Can you figure out why 3 nucleotides are used? Modified nucleic acids that contain 2 or 4 additional nucleotides besides A, C, G, & T have been created. Can you figure out how DNA could have 8 different bases and still replicate normally? DNA & especially RNA can contain modified bases. These range from the simple (thymine instead of uracil in RNA (rT)) to the complex (ms2t6A) to the downright weird (pseudouridine) to the absurd (glutamylQ). Their functions vary & can be mysterious; new modifications are still being found. Modified bases may form unmodified base pairs (U & rT pair with A in the same way) but sometimes form different base pairs (converting A to I causes it to pair with C) or are unable to form any base pair (m1I). Pieces have been made for rT, I, m1I, Cm, & pseudouridine in RNA. I occurs in tRNA at a position that is flexible, allowing it to shift around & form unconventional "wobble" pairs with U & even A in addition to the standard C. Do you see how this might happen? What other wobble pairing might you expect? Also included is the nucleotide form of ddC, a drug used against HIV. How do you think it blocks HIV? It, along with the similar ddA, etc., is also used to determine the sequence of nucleotides in DNA & RNA. Do you see how this can be done (hint: it is possible to separate DNA molecules by length)? module ddC(n,g,t,ll,lt,lh,lx,ly,ls,k,f,tf,cg) /*dideoxycytosine monophosphate (ddCMP), from anti-HIV drug ddC & terminator ddCTP used in DNA sequencing;
